ide-java can't resolve system libraries

[misabiko]

I receive the error "The type [type] cannot be resolved. It is indirectly referenced from required .class files." for java.lang.Object, java.lang.String and any other imports that's not from my project.

I'm on Windows 10, I have both Java 11 and 8 installed and JAVA_HOME is set to Java/jdk-11.0.2
The JDT server launches without issues. I've tried with both Linter and Diagnostics, but result is the same.
I also tried using vscode-java and I can launch the project no problem, same in command line.

Here's my .classpath file, it points to Java 1.8, but I can still compile on vscode, and I don't know the notation for Java 11.

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" path="src"/>
	<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-1.8"/>
	<classpathentry kind="output" path="bin"/>
</classpath>

Same problem here. On ubuntu, in ide-java's settings the java home is set to "/usr/lib/jvm/java-8-openjdk-amd64" and I receive warnings like "The type java.lang.Object cannot be received".

Did you find a solution ?

Use org.eclipse.jdt.launching.JRE_CONTAINER instead.

Use org.eclipse.jdt.launching.JRE_CONTAINER instead.

That worked for me. Removed everything after JRE_CONTAINER on the classpathentry

I have this on clean gradle project and JDK11:

Could not determine java version from '11.0.3'.
java.lang.IllegalArgumentException: Could not determine java version from '11.0.3'.
