Sean Patrick Floyd commented on MCOMPILER-135:
----------------------------------------------
OK now I see what you mean. What a mess. Maybe it would be best to introduce an
array parameter, as an array is what's passed to the compiler anyway. That way
we could catch all kinds of arguments. Something like this:
{code}
<arguments>
<argument>-Xmaxerrs</argument>
<argument>100</argument>
<argument>-Akey1=value1</argument>
<argument>-Akey2=value2</argument>
</arguments>
{code}

> Project: Maven 2.x Compiler Plugin
> Issue Type: Bug
> Affects Versions: 2.3.1
> Environment: JDK 1.6, Maven 2.2.1, Maven-Compiler-Plugin 2.3.1,
> Windows
> Reporter: Sean Patrick Floyd
> Attachments: AbstractCompilerMojo.java.2.patch,

> I have an annotation processor that supports multiple parameters and I have
> found that there is no way to set more than one of them at any given time
> from the Maven Compiler Plugin,
> Here's my setup.
> {code:xml}
> <plugin>
> <inherited>true</inherited>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-compiler-plugin</artifactId>
> <version>2.3.1</version>
> <configuration>
> <source>1.6</source>
> <target>1.6</target>
> <compilerArgument>-AaddResDir=src/main/webapp
> -Averbose=true</compilerArgument>
> </configuration>
> </plugin>
> {code}
> Javac needs the parameters added as separate Strings
> {code}[ ... , "-AaddResDir=src/main/webapp", "-Averbose=true"]{code}
> but the Compiler Plugin generates this code:
> {code}[ ... , "-AaddResDir=src/main/webapp -Averbose=true"]{code}
> which Javac will parse as
> {code}key:"addResDir" value="src/main/webapp -Averbose=true"{code}
> The map version "<compilerArguments>" is of no help either, because this
> {code}<Averbose>true</Averbose>
> <AaddResDir>src/main/webapp</AResDir>{code}
> will generate the output
> {code}[... , "-Averbose", "true", "-AaddResDir", "src/main/webapp"]{code}
> while this
> {code}<Averbose=true />
> <AaddResDir=src/main/webapp />{code}
> is not well-formed XML.
> Stepping through the compiler argument generation with the debugger I have
> not found a way to post-process the arguments, so please add a way to support
> multiple APT parameters because this is a major show-stopper.
