Summary: IllegalArgumentException when compiling plugin with
Eclipse batch compiler
Key: LOG4J2-2487
URL: https://issues.apache.org/jira/browse/LOG4J2-2487
Project: Log4j 2
Issue Type: Bug
Components: Plugins
Affects Versions: 2.11.1, 2.10.0, 2.8
Environment: In order to reproduce this bug, I created [this
project|https://github.com/katanagari7c1/ecj-error-log4j] with the minimal code
to test my scenario.
I reproduced this error on a Ubuntu 18.04 and OSX machine. Also tested with
versions 4.7 and 4.9 of the ECJ and using Java 8, both OpenJDK and Oracle.
Reporter: Javier Armendáriz
Recently I started using log4j 2 in my project and I created some custom
appenders and configuration factories using the @Plugin annotation.
It all worked fine and show no errors compiling in Eclipse 4.9 and IntelliJ
Idea. However, using the Eclipse batch compiler, my code fails with the
following stacktrace:
{noformat}
