Passing multiple parameters to Java 6 annotation processors with javac does not
work
------------------------------------------------------------------------------------
Key: MCOMPILER-135
URL: http://jira.codehaus.org/browse/MCOMPILER-135
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
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.
