------------------------------
Summary: IvyDE managed libraries not exported
Key: IVYDE-394
URL: https://issues.apache.org/jira/browse/IVYDE-394
Project: IvyDE
Issue Type: Bug
Affects Versions: 2.2.0.final
Environment: * Eclipse 2022-06 M2 (4.24.0 M2)
* IvyDE 2.2.0.final-201311091524-RELEASE
* OpenJDK 17.0.3+7-Debian-1deb11u1
* Debian GNU/Linux 11 (Bullseye)
Reporter: Harri T.
h2. Issue description
The classes of IvyDE managed libraries are not exported into a runnable JAR
file when a project JRE System Library is JavaSE-17.
h2. Steps for reproducing the issue
# Clone [the project|https://github.com/haba713/eclipse-ivyde-export-issue]:
{{git clone g...@github.com:haba713/eclipse-ivyde-export-issue.git}}
# Make sure that your Eclipse uses OpenJDK 17 and has IvyDE installed.
# Import the cloned project into Eclipse workspace.
# Right-click the class {{src/com.example/Main.java}} in the project tree and
choose Run as → Java Application. See the output: {{{}{"key":"value"}{}}}.
# Right-click the project and choose Export → Java → Runnable JAR file.
# Choose the launch configuration created on the step 4 above and choose also
Library handling: ◉ Extract required libraries into generated JAR. Click Finish.
# Try to run the generated JAR file:
$ java -jar eclipse-ivyde-export-issue.jar
Exception in thread "main" java.lang.NoClassDefFoundError: org/json/JSONObject
at com.example.Main.main(Main.java:8)

The class {{org.json.JSONObject}} and other JSON classes are not included in
the JAR file even though the library is listed in the [Ivy
dependencies|https://github.com/haba713/eclipse-ivyde-export-issue/blob/master/ivy.xml].
h2. Workaround: Use JRE System Library 1.8 instead
Add OpenJDK 8 to Eclipse and change Java Build Path → Libraries → JRE System
Library to JavaSE-1.8. After that
the IvyDE managed libraries are included in the runnable JAR file when it's
generated again.
