I want to migrate my Eclipse RCP application to Java 11 (OpenJDK 11).
And I have 3 issues related:
1. One of my plugin uses internal non-exported classes from package
com.sun.java.swing.plaf.windows
2. Second one uses jaxb-api classes (module jaxb-api has been removed in Java 9+)
3. Another plugins don't have compile errors related to Java 11
Questions/issues:
1. This post describes how to export internal packages in Eclipse: https://stackoverflow.com/questions/47262810/eclipse-java9-how-to-access-internal-javafx-packages.
But:
- my JRE System Library doesn't have Is Modular node in project properties dialog. So I need to open classpath file and add attribute manually, Then I'm able to add exports through Module Properties dialog
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-11">
<attributes>
<attribute name="module" value="true"/>
<attribute name="add-exports" value="java.desktop/com.sun.java.swing.plaf.windows=ALL-UNNAMED"/>
</attributes>
</classpathentry>
- I can resolve compile errors just adding attribute "add-exports" in classpath file, without specifying JRE as modular:
<classpathentry kind="con" path="org.eclipse.jdt.launching.JRE_CONTAINER/org.eclipse.jdt.internal.debug.ui.launcher.StandardVMType/JavaSE-11">
<attributes>
<attribute name="add-exports" value="java.desktop/com.sun.java.swing.plaf.windows=ALL-UNNAMED"/>
</attributes>
</classpathentry>
Do we need to specify JRE as modular? Which configuration is correct?
2. This post describes how to resolve removed modules: https://stackoverflow.com/questions/48204141/replacements-for-deprecated-jpms-modules-with-java-ee-apis
I've downloaded jaxb-api plugin and added it to my target platform. Do I need to update BREE in Manifest file and set Java 11 ?
3. For the plugins, that don't have any compile errors related to Java 11 do I need to update java version in Manifest file and set JRE as modular in classpath file every time?
Regards,
Serhii

Thank you for your reply, Stephan.

You didn't mention which version of Eclipse / JDT you are using. If this happens with latest, than this would be a bug. JRE >= 9 should always be recognized as modular
I'm using Eclipse 2018-12 (4.10.0) for Committers, JDT 3.16.
Just created a new Plug-in Project from Templates, JRE hasn't been recognized as modular. Checked the same in Eclipse for RCP devs (4.10, JDT 3.16), JRE has been recognized as modular. It looks like a bug for me.

This is strange, modifying modularity details should only have effect for elements on the Modulepath (i.e., Is Modular / "module=true")
Agree, maybe Eclipse recognizes JDK 11 as modular by default, I don't know..

OK, that's fairly recent :)

You mean one of the templates offered in the "New Plug-in Project" wizard, like "Hello, World Command"?
I just tried that and it correctly places the JRE on the module path, and the dialog says "Is Modular".
Wait: the "Java Build Path" shows info as expected, but .classpath doesn't need to show the "module" attribute because that information is inferred, indeed.
