Jiri Kraml created MCOMPILER-413:
------------------------------------

             Summary: Parameters does not work when only release is specified
                 Key: MCOMPILER-413
                 URL: https://issues.apache.org/jira/browse/MCOMPILER-413
             Project: Maven Compiler Plugin
          Issue Type: Bug
    Affects Versions: 3.8.1
         Environment: Arch Linux, OpenJDK 11.0.6.u10, Maven 3.6.3
            Reporter: Jiri Kraml


Compiling a project with the following maven-compiler-plugin configuration does not produce parameter name metadata in the class files:

{{<{color:#0033b3}configuration{color}>}}
{{    <{color:#0033b3}release{color}>9</{color:#0033b3}release{color}>}}
{{    <{color:#0033b3}parameters{color}>true</{color:#0033b3}parameters{color}>}}
{{</{color:#0033b3}configuration{color}>}}
{{}}

I believe this is a mistake, because
{{javac --release 9 -parameters Test.java}} 
will produce the metadata.

This behavior is due to dependency {{org.codehaus.plexus:plexus-compiler-javac:2.8.4}}, where in {{org.codehaus.plexus.compiler.javac.JavacCompiler}}, line 312, the function {{isPreJava18}} is called. This function does not evaluate the release property, only source and compilerVersion.

Available workarounds in {{pom.xml}} are additionally specifying {{source}} or explicitly specifying the {{-parameters}} parameter in the plugin configuration.
