Add support for profiling Gradle tasks

[ingokegel]

JProfiler 15 will add VS Code integration and as part of that effort we would like to support profiling Gradle tasks as well. To accomplish that, we need to add an -agentpath VM parameter to a Java invocation that is launcher from the Gradle build.

To allow profilers to add their VM parameters, a registerToolOptionsProvider function was added to the API. When a build is run, the VM parameters are queried from all registered tool option providers, concatenated and sent to the Gradle server where they are added to the JAVA_TOOL_OPTIONS along with the debugger VM parameter.

Hi @ingokegel,

Thank you for your contribution.

The PR looks good to me.

May I ask if there is any bit I can use to test the integration?

[ingokegel]

@jdneo I've added a commit with a test extension that sets a system property via the new mechanism. Is that what you were looking for?

[jdneo]

Thank you @ingokegel.

Sorry I did not say it clearly. (It's good to have it for testing though!) I would like to know from customer perspective, how they can use this new feature? Is that a JProfiler vscode extension using this new API? How is the E2E experience looks like?

From our side, these can be some useful materials that we can mention and tell our customers in our feature update blog for VS Code Java.

Is that a JProfiler vscode extension using this new API?

Yes, exactly. The JProfiler VS Code extension has a toggle action for profiling. If enabled, launch configurations are profiled and the JProfiler UI is opened when a launch configuration is started. Benefits of such an IDE integration include:

• You can profile existing launch configurations without any additional setup in JProfiler
• Source navigation from JProfiler will be performed in the IDE.
• JProfiler is informed about the packages in the source roots and that information is used to set filters for method call recording

For the VS Code Gradle extension, we need this new functionality so that JProfiler can insert an additional VM parameter that loads the profiling agent when a Gradle task is executed.

How is the E2E experience looks like?

The user will not be dealing with the API, it is just used by the JProfiler VS Code extension. Other profilers can also use this API, there is nothing specific regarding JProfiler about it.

[jdneo]

May I ask is the JProfiler VS Code extension available now? I tried to find it in the marketplace but did not find it.

[ingokegel]

No, it is not published yet because it requires JProfiler 15 which has not yet been released.

[jdneo]

I see.

Would you mind me holding this PR until the JProfile extension is about to be released?

If you need a vsix with this change, I can build one for you.

[ingokegel]

No problem, I will let you know once we have an RC.

If you need a vsix with this change, I can build one for you.

Thanks, but I did manage to build the vsix for testing the JProfiler VS Code extension.

[jdneo]

OK, cool!

[ingokegel]

@jdneo JProfiler 15 has been released! The VS Code integration can be found at

https://marketplace.visualstudio.com/items?itemName=ejtech.jprofiler

It already contains support for profiling Gradle tasks if this pull request is merged.

[jdneo]

Thank you @ingokegel
