VsCode: No such compiler 'eclipse'

Daniel615be · January 27, 2026, 10:31am

Platform information:
- Hardware: x64
- OS: Windows 11
- Java Runtime Environment: OpenJDK Runtime Environment Zulu21.42+19-CA
- openHAB version: 5.2.0

Issue of the topic: The compilation on VsCode stops working.
After a merge this morning, I’m unable to compile any binding.
The last working compilation was on 23/01/2026.

[ERROR] Compiler 'eclipse' could not be instantiated or injected properly. If you spelled the compiler ID correctly and all necessary dependencies are on the classpath, then next you can try running the build with -Dsisu.debug, looking for exceptions. TypeNotPresentException caused by UnsupportedClassVersionError might indicate, that the compiler needs a more recent Java runtime. IllegalArgumentException in ClassReader.<init> might mean, that you need to upgrade Maven.
[DEBUG] Adding D:\Development\openhab-addons\bundles\org.openhab.binding.velbus\target\generated-sources\annotations to the project compile source roots but NOT the actual compile source roots:

The error is introduced by the commit 9039ea0 (PR #20135).

Daniel615be · January 27, 2026, 4:30pm

VsCode compilation error since commit 9039ea0 · Issue #20154 · openhab/openhab-addons

Daniel615be · January 27, 2026, 4:39pm

Revert back plexus-compiler-eclipse to version 2.12.1 is a workaround to the problem.

Daniel615be · January 27, 2026, 9:42pm

The final solution was to update Maven to the last version (currently 3.9.12)
