Unbound classpath container: JRE System Library (in test, OS X, tycho)

Create a desktop shortcut for the launcher relevant to your operating system. Add the directory with IntelliJ IDEA command-line launchers to the PATH environment variable. Add an item Open Folder as Project to the system context menu (when you right-click a folder) Associate specific file extensions with IntelliJ IDEA to open them with a double. Jul 17, 2019 Java is a runtime environment maintained by Oracle that you must install on your Mac to be able to run applications written using the Java programming language. Moreover, Java allows developers to make apps available on multiple operating systems at the same time because Java-based utilities will run on any platform that can integrate the runtime environment.

Unbound classpath container: JRE System Library (in test, OS X, tycho)[message #1817520]

Hello,
This is a bit of a weird problem: when I run 'mvn verify' on an OS X system, one of my plugin tests fails because the workspace created cannot locate the JDK.
The test is a slightly complicated integration test, but the problem is quite simple: the JDT project created in the test workspace cannot resolve the JRE libraries and when I build my 'test project' in the 'test workspace' I have an assertion that verifies there are no problem markers, only there's 2 of them: one that says the classpath container for the JavaSE-1.8 execution environment is unbound and the other saying that the 'test project' cannot be built until the callpath issue is resolved.
This happens only when building with maven and only on OS X. If I run the test from within the Eclipse workspace on OS X everything works fine. It is only when I run 'mvn verify' where tycho-surefire-plugin kicks in that the problem arises. Furthermore on Windows 10 I can run 'mvn verify' just fine.
I've made sure my JAVA_HOME is pointing to the correct location using /usr/libexec/java_home (I have Oracle JDK 8 Update 231 on that laptop). It's really weird because maven itself uses that JDK compiler (if you run maven with a JRE it would fail saying it needs a JDK) so I know that the configuration is ok (the JDK is first in the PATH and the JAVA_HOME points to it).
I'm actually a bit lost with regard to what to check. Any suggestions on whatever you think I could investigate are welcome.
Quote:

UPDATE: I've added a 'TimeUnite.MINUTES.sleep(2)' statement in the beginning of the first unit test. This allows me to interact with the instance that pops up, as it waits for the unit test thread to proceed. I try to create a new Java Project manually and see in the first page of the dialog the warning 'The default JRE could be detacted. To add a JRE manually go to the JREs preference page'. Clicking on the link and adding the JRE at '/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home' fixes the test workspace, so when the 2-minute time out elapses the test proceeds and completes successfuly. So indeed it is a case of the JRE not being detected..

According to the FAQ Find the JVM entry, Eclipse ignores JAVA_HOME and uses 'eclipse.ini' and the system path to identify the JRE. I've made sure to put '/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home/bin' as the first entry in PATH but still the JRE is not detected.

It appears that the VM installation code explicitly ignores Mac OS X installations as can be seen in StandardVMType.detectInstallLocation().
It seems to me that macosx-specific feature fragments may be missing when I run the integration tests. Will be looking into that next..

Adding an explicit dependency on 'org.eclipse.jdt.launching.macosx' resolves this!
