Guillaume Dumont updated LOG4J2-1937:
-------------------------------------
Environment:
Java 1.8.0_131
was:
MacOSX El Capitan, Java 1.8.0_131
> Including log4j-core yields a compilation warning with -Xlint:all
> -----------------------------------------------------------------
>
> Key: LOG4J2-1937
> URL: https://issues.apache.org/jira/browse/LOG4J2-1937
> Project: Log4j 2
> Issue Type: Bug
> Affects Versions: 2.8.2
> Environment: Java 1.8.0_131
> Reporter: Guillaume Dumont
> Attachments: TestProject.zip
>
>
> It seems that starting from log4j2 (2.0+), including {{log4j-core}} to a
> project that invokes {{javac}} with the option {{-Xlint:all}} will show the
> warning below for all annotations in the project.
> {noformat}
> warning: No processor claimed any of these annotations:
> org.junit.Test,org.junit.Rule,org.junit.Ignore,org.junit.Before,org.junit.After
> {noformat}
> I could reproduce it using a small project by putting the following in the
> gradle file:
> {code}
> dependencies {
> testCompile group: 'junit', name: 'junit', version: '4.11'
> compile group: 'org.apache.logging.log4j', name: 'log4j-core', version:
> '2.0'
> }
> tasks.withType(JavaCompile) {
> options.compilerArgs << "-Xlint:all"
> }
> {code}
> After a lot of research, the only workaround that I've seen suggested is
> basically to suppress this warning by using {{-Xlint:-processing}} instead.
> However this warning is definitely triggered by log4j2, which makes me think
> that this is where the root cause lies. In term of concrete impact, the
> annotations seem to work correctly.
