Olivier Lamy updated MCOMPILER-172:
-----------------------------------
Attachment: groovy-project-with-new-plexus-compiler.zip
> Breaking change to plexus compiler api 1.9
> ------------------------------------------
>
> Key: MCOMPILER-172
> URL: https://jira.codehaus.org/browse/MCOMPILER-172
> Project: Maven 2.x Compiler Plugin
> Issue Type: Bug
> Reporter: Olivier Lamy
> Fix For: 2.6
>
> Attachments: groovy-project-with-new-plexus-compiler.zip
>
>
> in 1.8.1:
> {code}
> CompilerConfiguration.getCustomCompilerArguments() returns LinkedHashMap
> {code}
> in 1.9:
> {code}
> CompilerConfiguration.getCustomCompilerArguments() returns Map<String,
> String>
> {code}
> This means that a plugins compiled against one version will not work
> against the other (java.lang.NoSuchMethodError is thrown). Is this
> right? Am I missing something or must there be a strict dependency on
> plexus-compiler-api (and hence the maven-compiler-plugin)?
> I am attaching a failing maven project. When you run mvn clean compile on
> this project, it will fail with this error:
> {code}
> ERROR] Failed to execute goal
> org.apache.maven.plugins:maven-compiler-plugin:2.5:compile (default-compile)
> on project org.codehaus.groovy: Execution default-compile of goal
> org.apache.maven.plugins:maven-compiler-plugin:2.5:compile failed: An API
> incompatibility was encountered while executing
> org.apache.maven.plugins:maven-compiler-plugin:2.5:compile:
> java.lang.NoSuchMethodError:
> org.codehaus.plexus.compiler.CompilerConfiguration.getCustomCompilerArguments()Ljava/util/LinkedHashMap;
> {code}
> If you edit the pom and change the maven-compile-plugin dependency to 2.3.2,
> the clean compile will succeed.
> My suspicion is that if you change the signature of
> getCustomCompilerArguments to public LinkedHashMap<String, String>
> getCustomCompilerArguments(), this will succeed.
