Setting Up a Dev Environment

Who This Guide Is For

We recommend this guide for users who:

• Write or maintain a large number (10+) of custom scripts regularly

• Collaborate on a team of 3 developers or more

• Want to implement standard software development practices (and tools) alongside their scripts, for example:

  • Version control (Git)

  • Configuration as code (YAML)

  • Automated testing (Spock)

  • Continuous integration

• Want to keep their scripts in a centralized place that isn’t simply a script root directory on their server

• Want all the benefits of working with IntelliJ IDEA, for example:

  • Efficient script-writing and less log hunting

  • Quick access to the Atlassian APIs

  • Code auto-completion, syntax checks, and other IDE features

This is a quick-start guide for users who could benefit from connecting ScriptRunner to tools such as Git, IntelliJ, and Maven, without mastering them. The goal is to give useful tools to the average scripter without holding back more experienced developers.

Requirements

The software and hardware requirements for this guide follow:

Software

• Java SE Development Kit 8 (JDK 8)

• Git

• IntelliJ IDEA

• Atlassian-SDK

• Atlassian Maven (installed with the Atlassian SDK)

Which Maven

We recommend using the Maven binary shipped with the atlassian SDK as this is Atlassian's own implementation of Maven specifically designed for use with developing atlassian plugins. Standard Maven installations might not be able to resolve all the required dependencies without additional configurations.

You can find how to install the atlassian SDK here:
Windows
Linux/Mac

Once installed you will need to know where the Maven binaries are located (e.g: atlas-mvn). You can find this by running:

atlas-version 

(Look for the ATLAS Maven Home value)

Inside IntelliJ, you can then configure your Maven configuration to point to the atlassian Maven binaries using the ATLAS Maven Home directory as the Maven home path.

Hardware

Your memory needs vary based on the Atlassian host application that you’re working with. Here are Atlassian’s recommendations:

• Jira -  2GB of RAM

• Confluence -  6GB of RAM

• Bitbucket -  3GB of RAM

The ScriptRunner Samples Project

This project contains script plugins for the ScriptRunner Suite (Jira, Confluence, and Bitbucket Server). The following tasks lead you through working with the Scriptrunner Samples project to connect the tools.

Import the Project into IntelliJ

1. Check out the project and import it into IntelliJ.

   The ScriptRunner samples Git  URL  is:  https://bitbucket.org/adaptavistlabs/scriptrunner-samples

2. Once the project has been imported, IntelliJ downloads dependencies.

   This takes a while, but let it finish before moving on to the next task.

Set a JDK for the Project

Java Development Kit 8 should be configured as the SDK for the project. There’s a chance the SDK may already be configured, but if not, you can find instructions by clicking the links below.

1. Configure a  Global SDK.

2. Configure your  Project SDK.

3. Configure your  Module SDK.

Build and Run Jira/Confluence/Bitbucket with the Sample Plugin

If you have fulfilled the above requirements and tasks, you should now be able to build the sample plugins.

1. Inside a terminal, you can start each application with its respective command:

   Make sure to `cd` into the subdirectory for your required module first

   Subdirectory	Command
   jira	atlas-mvn jira:debug
   confluence	atlas-mvn confluence:debug
   bitbucket	atlas-mvn bitbucket:debug
   bamboo	atlas-mvn bamboo:debug

   Those commands should start a locally running instance of the application at:  http://localhost:8080/<application>  and you should see something like this in your terminal: 
   
   

2. Login using the following credentials:

   • Username:  admin

   • Password:  admin

3. Complete the application’s setup screens, if prompted.

4. Test to make sure everything has started properly by following these steps:

   1. Navigate to the Script Console, and then switch to the  File  tab.

      

   2. Start typing the name of the sample script that's installed in each plugin (ScratchScript.groovy), and then click the suggestion. 

   3. Click  Run

      You should see the string returned by that script in the  Results  tab.

      

Script Roots Information

The base pom adds the following script roots to the development environment only:

• <module>/src/main/resources

• <module>/src/test/resources

• <module>/src/test/groovy

Any scripts inside these directories can be run from the Script Console (or any other ScriptRunner extension point such as event listeners) without specifying a full path (like you did with the  ScratchScript.groovy  file above).

Advanced IntelliJ IDEA Configurations

Read on for some advanced configuration options that will make your scripting experience even better.

Create Debug Configuration in IDEA

A debugger can be helpful for complex scripts. Follow these steps to create a run configuration for starting a debugger:

1. Select  Run  >  Edit Configurations  in the top menu bar.

2. Press the  +  button, and then select  Remote.

3. Set a name for your debug configuration (e.g. "Jira").

4. Set the debug port to  5005.

5. Click on the  Logs  tab, and then press the  +  button.

6. Enter an  Alias  (e.g.  Jira logs).

7. Navigate to the location of your logs by using the  Browse  button.

   

   The log files should be at the following locations:

   • Jira -  scriptrunner-samples/jira/target/jira/home/log/atlassian-jira.log

   • Bitbucket -  scriptrunner-samples/bitbucket/target/bitbucket/home/log/atlassian-bitbucket.log

   • Confluence - The log file is not be present in the target directory, but it is written to the  Console  tab in IntelliJ when you run  confluence:debug.

     The  target  directory is only present if the application has been previously built. If you’ve followed all of the tasks in this guide, you completed this in the  Build and Run Jira/Confluence/Bitbucket with the Sample Plugin  section.

8. Click  OK.

   The debug configuration should look approximately like this:

   
9. Click  Apply, and then click  OK.

10. Since you already started the application in the previous steps, click  Run  >  Debug Jira  (or whichever debugger you created) to start debugging your application.

    That action starts the debugger, and a window like this one should show up in a lower area of IDEA:

    

Debug a Groovy Script

You can use the debugger you just created with a Groovy script.

1. In IDEA, open  ScratchScript.groovy.

   Each application has its own so make sure you open the correct one.

2. Set a Breakpoint  on the line the string begins on.

   

3. Execute your script via the  Script Console.

   The debugger should stop the execution of the script at the location of your breakpoint.

   

4. Use the inspector to:

   • Step through the code

   • Mid-execution, look at the values of variables in your script

   • Mid-execution,  evaluate a Groovy code fragment

     For other uses, consult JetBrains'  Debugging  documentation.

5. Click the green run button to resume the execution.

   

Connecting IntelliJ IDEA with the Atlassian Source Code

One of the biggest benefits of writing your code in IDEA is that you can access the JavaDoc directly in the IDE instead of needing to go to the API’s documentation website.

If you have purchased a license from an Atlassian product, you will have access to the  Source Download  page.

Using Jira as an example, follow these steps to create a new Groovy script to see the connection working:

1. Create a new file called  UsersCount.groovy  inside the  src/main/resources/  script root.

2. Use the following code in the file:

   import com.atlassian.jira.component.ComponentAccessor
   import com.atlassian.jira.user.util.UserManager
   
   def userManager = ComponentAccessor.getUserManager() as UserManager
   def message = "My instance contains ${userManager.totalUserCount} user(s)."
   
   log.warn(message)

3. Run  UsersCount.groov  using the Script Console.

   1. In the  Logs  tab, you can see a message stating "My instance contains X users."

      

   2. You should see the same message in the  Jira Logs  tab of your IntelliJ debugger.

      

Browse the Java API

The  UserManager  class can do many different things. Follow one of these steps to explore its capabilities.

• In IntelliJ, type  userManager., and you will see the properties and methods available to be used.

  

• In, IntelliJ, navigate to the class file itself by holding down  CTRL  (or  CMD  in OSX) and clicking on the class name. Try this for the  UserManager  class located at the end of line 4. You will see something like this:

  

  The decompiler already gives you a lot of information about the class, but you can go even further and see the entire implementation of it.

  If you click the  Choose Sources…​  link, and then select the folder that contains the application’s source (which you downloaded earlier), the source for the class is shown. Then, the IDE will provide better parameter names and inline JavaDoc.

  You may have to do this multiple times, once for each dependency (jira-software,  jira-servicedesk  etc). In each case, just point to the root of the downloaded sources, select everything, and let IDEA configure it.

Advanced Plugin Configuration

There are a number of settings in the plugin’s  pom.xml  file that you may want to change to suit your needs while writing your scripts.

Customize Product Versions

The project’s parent pom sets a lot of default values for the versions of the libraries to be used when writing your scripts. Those default values can be changed if you are going to write scripts for a different version of the Atlassian applications. You can change them by editing the  <properties>  section of your pom.xml.

For example, to set the Jira version to 7.13.11, your properties block might look like:

xml
<properties>
    <jira.version>7.13.11</jira.version>
</properties>

Customize the Scriptrunner version

If you want the development environment to start with a specific ScriptRunner version you can override the default by adding a property to your application-specific local pom file.

For example:

For Jira, if you want ScriptRunner 6.40.0 to be installed when you run atlas-mvn jira:debug you can edit the /scriptrunner-samples/jira/pom.xml file and inside the properties XML tag add:

<scriptrunner.version>6.40.0</scriptrunner.version>

Adding Additional Applications

Adding additional applications is done inside the  <applications>  block.

For example, if you are writing a plugin for Jira, you may require Jira Software, or Jira Service Management. Those two have been added to  jira/pom.xml  for you, but for others you will need to add them. To make sure they get installed, uncomment out the application(s) you would like. An example of this code is shown below:

<applications>
    <!-- Include Jira Software features -->
    <!--
    <application>
        <applicationKey>jira-software</applicationKey>
        <version>${jira.software.version}</version>
    </application>
    -->

    <!-- Include Jira Service Desk features -->
    <!--
    <application>
        <applicationKey>jira-servicedesk</applicationKey>
        <version>${jira.servicedesk.version}</version>
    </application>
    -->
</applications>

Changing the Default HTTP Port

The base pom sets all applications to run on port  8080  for consistency, rather than their defaults. That can be changed by adding a  <httpPort>  entry to the configuration block of your AMPS plugin (jira-maven-plugin, confluence-maven-plugin, bitbucket-maven-plugin). An example of this code is shown below:

xml
<plugin>
    <groupId>com.atlassian.maven.plugins</groupId>
    <artifactId>jira-maven-plugin</artifactId>

    <configuration>
        <!-- Other code here... -->
        <httpPort>2990</httpPort>
        <!-- Other code here... -->
    </configuration>
</plugin>

Go Further

The next time you want to create and debug a new script, you will just need to add a new Groovy script to your IDEA project and run the <application>:debug Maven goal to test it. As your script library grows, you may find you need even more out of your local development environment.

Development Lifecycle

Do you find copying and pasting scripts between IntelliJ and the ScriptRunner web interface tedious? There are two better ways: the Script Editor and a script plugin.

• Using the Script Editor, you can edit and create files directly from ScriptRunner’s UI. Check out the ScriptRunner Script Editor documentation for more information.

• The whole environment you just set up is actually a full blown Atlassin plugin development. Take a look at the documentation on Create a Script Plugin for more information on how to use that environment to develop and package your scripts for deployment in test and production instances.

Execute Tests

For automated testing in ScriptRunner in the project that you just set up, you can add tests under <module>/src/test/resources. You can then run them with our built-in script located under Administration > Built-In Scripts > Test Runner. See Testing documentation for more information.

Use an External Tool for Running Scripts Against Jira/Confluence/Bitbucket

One handy tool for debugging is adding an external tool in IntelliJ to run an arbitrary Groovy script against ScriptRunner.

We will use Jira as an example, but the same can be done for Confluence and Bitbucket.

1. Navigate to IntelliJ Preferences > Tools > External Tools.

2. Click + and fill in the following fields:

   • Name: Run in Jira

   • Program: curl

   • Arguments: -u admin:admin --header "X-Atlassian-token: no-check" -X POST --data "scriptFile=$FilePathRelativeToSourcepath$" http://localhost:8080/jira/rest/scriptrunner/latest/user/exec/

     Make sure your application’s base URL and port are correct.

   • Working directory: $ProjectFileDir$

   • The fields should look like this:

     

3. Click OK

4. Invoke the test by running Tools > External Tools > Run in Jira in the top menu bar of IntelliJ.

   This will POST the body of the script file you’re working with to your locally running Jira server and execute it, just as if you’d copy-and-pasted the code into the Script Console and clicked Run.
