Access to ${target_home} in Oomph setup [message #1774772]

Hi everyone,

in our Eclipse N4JS https://github.com/eclipse/n4js, we would like to configure the default product in the Run Configuration -> Program to Run -> "Run a product".

In the subsection "Program to Run" in Eclipse documentation https://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.pde.doc.user%2Fguide%2Ftools%2Flaunchers%2Feclipse_main.htm it says
Quote:

The Program to Run section is where you specify the product or application to test.

The product combo box is populated with the IDs of all products (org.eclipse.core.runtime.products extensions) defined in the workspace and target plug-ins. The product ID that is initially selected is the default product as specified by the eclipse.product key in the config.ini file that is located in the ${target_home}/configuration directory. The ${target_home} variable refers to the location of the target platform as specified on the Windows > Preferences... > Plug-in Development > Target Platform preference page . In the Eclipse SDK, the default product ID is org.eclipse.sdk.ide.

I tried to create a config.ini file in the Oomph setup file, but the variable ${target_home} is not available.

Does anyone have any hints?

Thanks!

PS: In my test case, the value of ${target_home} of a running Eclipse instance is:

/Users/quang.tran/oomph/TESTN4JS/ws/.metadata/.plugins/org.eclipse.pde.core/.install_folders/1508414124544

I'm not sure I completely follow. What are you trying to accomplish exactly? What are you trying to set in the config.ini? A launch configuration can be located in one of your projects and can be committed to git, fully configured...

Hi Ed,

Thanks a lot for your reply. I have visualized what I want to achieve in the screenshot

Right now, whenever we create a new Junit Plugin Test run configuration, the product ID chosen in the combobox Run a Product is org.eclipse.platform.ide. I would like this to be automatically set to org.eclipse.n4js.product.product.

In order to do this, according to the Eclipse documentation I mentioned in my previous post, we have to put the following entry

eclipse.product=org.eclipse.n4js.product.product

into a config.ini file and this file must be located in ${target_home}/configuration folder.

These variables they refer to in the documentation are substitution variables that you can use, for example, in launch configurations themselves. If PDE doesn't directly populate an system/environment variable with this location, then there is nothing I know of that makes that location information available directly in the running IDE for use in a setup.

Hi Ed,

yeah, that's the problem. I have ended up with the hack where I create a launch task in Oomph that executes the a run configuration. The run configuration is associated with a Java class and the variable ${target_home} is passed as argument so that I can access it inside the main method of the Java class in order to know where to put the config.ini file.

And in order to do that, I need to execute a build task (ProjectsBuild) first. The problem is, the build task is executed again and again when we restart the IDE. Is there anyway to tell Oomph to execute the build task once for the first oomph only ?
