Hi all,
Let me start with a new edit #2 as I have found what may be the cause:
------------------------------------------
EDIT2: The new P2 director application may have a bug in path separators
As explained below, installations created with P2 director in Eclipse 4.21 fail to start. I tried to start the installation created and found that it has not handled the Windows '\' path separator properly, hence the installation cannot be found. In startup console log I see:
WARNING: Using incubator modules: jdk.incubator.vector, jdk.incubator.foreign
Install location:
file:/C:/Users/me/UsersmedevrootappsEclipse-2021-09MyEclipse-2021-09
...
The path should read file:/C:/Users/me/devroot/apps/Eclipse-2021-09/MyEclipse-2021-09 so it looks like the install locatiojn I provided with "-destination C:\Users\me\devroot\apps\Eclipse-2021-09\MyEclipse-2021-09" had all the '\' treated as escaping (resulting in them disappearing) and then the entire string was appended to the base location.
------------------------------------------
I know the new installer is awesome, but I prefer to provision my Eclipse using P2 director. For years this has worked for me, but for 2021-09 it suddenly stopped. I don't do anything fancy, just run the P2 director from command line, giving it a list of repos and features like this:
C:\Users\me\devroot\apps\Eclipse-2021-09\eclipse\eclipse.exe -nosplash -application org.eclipse.equinox.p2.director -p2.os win32 -p2.ws win32 -p2.arch x86_64 -profile SDKProfile -profileProperties org.eclipse.update.install.features=true -bundlepool C:\Users\me\devroot\apps\Eclipse-2021-09\shared_bundles_pool-2021-09 -destination C:\Users\me\devroot\apps\Eclipse-2021-09\MyEclipse-2021-09 -repository https://www.mirrorservice.org/sites/download.eclipse.org/eclipseMirror/releases/2021-09,https://www.mirrorservice.org/sites/download.eclipse.org/eclipseMirror/tools/cdt/releases/10.4 -installIU org.eclipse.cdt.feature.group,org.eclipse.egit.feature.group,org.eclipse.xtext.sdk.feature.group,org.eclipse.m2e.logback.feature.feature.group,org.eclipse.m2e.feature.feature.group,org.eclipse.epp.mpc.feature.group,org.eclipse.xtend.sdk.feature.group,org.eclipse.sdk.ide
This provisions my installation successfully (as usual) by when I try to run MyEclipse-2021-09\eclipse.exe I get a dialog box saying the "Java was started but returned exit code=13".
Note that C:\Users\me\devroot\apps\Eclipse-2021-09\eclipse simply contains the extracted platform runtime binary eclipse-platform-4.21-win32-x86_64.zip.
My JDK is 64-bit and running the same for 2021-06 (and 2021-03 and several before those) works fine:
PS C:\Users\me> mvn -version
Apache Maven 3.8.1 (05c21c65bdfed0f71a2f2ada8b84da59348c4c5d)
Maven home: C:\Users\me\.sdkman\candidates\maven\3.8.1\bin\..
Java version: 11.0.11, vendor: AdoptOpenJDK, runtime: C:\Users\me\.sdkman\candidates\java\11.0.11.hs-adpt
Default locale: en_GB, platform encoding: Cp1252
OS name: "windows 10", version: "10.0", arch: "amd64", family: "windows"
Has something changed in P2 director in 4.21? Why is the installation it creates not startable?
EDIT: I also tried Oracle's OpenJDK with same results, so AdopyOpenJDK does not seem to be the issue. I get the same behaviour with:
PS C:\Users\me> mvn -version
