[jira] Updated: (MNG-862) Compiler arguments cause maven-compiler-plugin to fail when forked
[ http://jira.codehaus.org/browse/MNG-862?page=all ]
Rod Coffin updated MNG-862:
---------------------------
Attachment: patch-862.txt
This bug seems to be caused because the Plexus MapConverter creates a TreeMap and the CompilerConfiguration expects a LinkedHashMap. These two are not directly subsitutable. My patch simply converts the TreeMap to LinkedHashMap. It would also be worthwhile considering whether the CompilerConfiguration should pass compiler arguments as a list instead of a map.

> Adding a compiler argument to a forked compiler causes maven to fail. An example plugin configuration causing this error is:
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-compiler-plugin</artifactId>
> <configuration>
> <fork>true</fork>
> <executable>C:\oss\aspectj1.5\bin\ajc</executable>
> <source>1.5</source>
> <target>1.5</target>
> <compilerArguments>
> <sourceroot>src/main/java</sourceroot>
> </compilerArguments>
> </configuration>
> </plugin>
