Johan Janssen created MCOMPILER-460:
---------------------------------------

             Summary: Compiler doesn't show detailed information with the Maven Toolchains
                 Key: MCOMPILER-460
                 URL: https://issues.apache.org/jira/browse/MCOMPILER-460
             Project: Maven Compiler Plugin
          Issue Type: Bug
    Affects Versions: 3.8.1
         Environment: Windows Java 16
            Reporter: Johan Janssen


I've created an example to showcase the issue: https://github.com/johanjanssen/mavenexample

When running without the Toolchains on Java 16

{{}}
{code:java}
mvn compile or docker build -t mavenexample -f DockerfileJava16 .  
{code}
Gives 

{{}}
{code:java}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project broken: Fatal error compiling: java.lang.IllegalAccessError: class lombok.javac.apt.LombokProcessor (in unnamed module @0x21bd20ee) cannot access class com.sun.tools.javac.processing.JavacProcessingEnvironment (in module jdk.compiler) because module jdk.compiler does not export com.sun.tools.javac.processing to unnamed module @0x21bd20ee -> [Help 1]{code}
{{}}

When running with the Toolchains on Java 16

{{}}
{code:java}
mvn compile -Ptoolchain or docker build -t mavenexample -f DockerfileJava16Toolchain . 
{code}
Gives 

{{}}
{code:java}
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile) on project broken: Compilation failure -> [Help 1]{code}
{{}}

So the Toolchain setup lacks quite some information about the compilation failure.

Is it possible to get the same error information when using the toolchain?

My usecase is having a quick way to build the same code with 2 different versions of Java. To show one version works and the other fails. It's also possible with Docker or setting the JAVA_HOME variable. But I was curious to see if it would work with toolchains as well.
