[Inquiry] JustJ installation creates new eclipse.ini instead of updating <app>.ini [message #1834024]

Hello,

I tested JustJ installation in custom product (its based is eclipse-platform-4.17-win32-x86_64), where it used app.exe and app.ini. After installation, JustJ created new eclipse.ini to put "vm" arg instead of updating app.ini. Any inputs how to tweak it to update app.ini instead? Please advise.

Thank You!

I use this to build the Eclipse Installer and the p2 director, as driven by Tycho, modifies the eclipse-inst.ini during the build. But I didn't do anything special to make that work.

What exactly do you mean by "After installation...". Do you mean during the Tycho build?

Hi Ed Merks,

Here's what I did.
1. Using eclipse-platform-4.17-win32-x86_64, replace "eclipse.exe" with our pre-built "myapp.exe"
2. Replace "eclipse.ini" with "myapp.ini"
4. Launch "myapp.exe"
5. install plugins to create our product and restart
6. Install JustJJre, using it's update site https://download.eclipse.org/justj/jres/11/updates/release

Result:
1. JustJ created new "eclipse.ini" which contains "-vm" arg and "myapp.ini" wasn't updated. Please see below screenshot.

Thanks,

No doubt somewhere in the metadata of the installation it still knows that the files should be called eclipse.exe, eclipsec.exe and eclipse.ini, so any update to those, or touch points to change those, will use the old/expected names.

This is not how you should create a branded product. You should build one using Tycho with your own *.product file with the proper branded name so that the metadata is consistent with the artifact names.

To be more specific, in the installation's p2/org.eclipse.equinox.p2.engine/profileRegistry folder there will be a named profile folder, *.profile which in turn contains *.profile.gz files. Here there are things like this (for the case of the installer product):

    <property name='eclipse.touchpoint.launcherName' value='eclipse-inst'/>
...
      <touchpointData size='1'>
        <instructions size='2'>
          <instruction key='configure'>
            setLauncherName(name:eclipse-inst)
          </instruction>
          <instruction key='unconfigure'>
            setLauncherName()
          </instruction>
        </instructions>
      </touchpointData>

The touch point for setting the VM itself makes no mention of the name of the *.ini:

      <touchpointData size='1'>
        <instructions size='4'>
          <instruction key='uninstall'>
            org.eclipse.equinox.p2.touchpoint.eclipse.setJvm(jvm:null);
          </instruction>
          <instruction key='zipped'>
            true
          </instruction>
          <instruction key='install'>
            org.eclipse.equinox.p2.touchpoint.eclipse.setJvm(jvm:${artifact.location}/jre/bin);
          </instruction>
          <instruction key='manifest'>
            Bundle-SymbolicName: org.eclipse.justj.openjdk.hotspot.jre.minimal.stripped.win32.x86_64;singleton:=true&#xA;Bundle-Version: 15.0.0.v20200918-1211&#xA;Fragment-Host: org.eclipse.justj.openjdk.hotspot.jre.minimal.stripped;bundle-version=&quot;[15.0.0,15.0.1)&quot;
          </instruction>
        </instructions>
      </touchpointData>

I assume the *.ini is computed from the <eclipse.touchpoint.launcherName>.ini.

Hi Ed Merks,

I tried to change the launcher property value with our product name (ie. "myapp"), and yes it works perfectly.. But you are correct, we may consider building our product using *.product file to make everything consistent.
Thank you so much again for your help.

regards,
Lea
