Key: MGROOVY-180
URL: http://jira.codehaus.org/browse/MGROOVY-180
Project: GMaven
Issue Type: Bug
Components: tools
Affects Versions: 1.0-rc-3
Environment: -
Reporter: Jason Smith
Assignee: Jason Dillon
> I have the following plugin definition for defining a MANIFEST in my
> JAR file.
>
> Note that <addExtensions/> is "true".
> <plugin>
> <groupId>org.apache.maven.plugins</groupId>
> <artifactId>maven-jar-plugin</artifactId>
> <configuration>
> <archive>
> <index>true</index>
> <manifest>

> <mainClass>com.infotrustgroup.util.commandline.Main</mainClass>

> <packageName>com.infotrustgroup.buildtools</packageName>
> <addClasspath>true</addClasspath>
> <addExtensions>true</addExtensions>

> This adds entries for all the extension libraries into the JAR file,
> like this:
> ...
> joda-time-Extension-Name: joda-time
> joda-time-Implementation-Version: 1.5.2
> gmaven-runtime-1.5-Extension-Name: gmaven-runtime-1.5
> gmaven-runtime-1.5-Implementation-Version: 1.0-rc-3
> slf4j-api-Extension-Name: slf4j-api
> slf4j-api-Implementation-Version: 1.5.0
> gmaven-feature-support-Extension-Name: gmaven-feature-support
> gmaven-feature-support-Implementation-Version: 1.0-rc-3
> gmaven-feature-api-Extension-Name: gmaven-feature-api
> ...
>
> Now when I run Java with -jar, like this:
> java -jar "%~dp0\lib\BuildTools-1.0.6-SNAPSHOT.jar" "%~f0"
> com.infotrustgroup.buildtools.commands.Build %*
>
> I get the following exception:
> Exception in thread "main" java.io.IOException: invalid header
> field name: gmaven-runtime-1.5-Extension-Name
> at java.util.jar.Attributes.read(Attributes.java:416)
> at java.util.jar.Manifest.read(Manifest.java:182)
> at java.util.jar.Manifest.<init>(Manifest.java:52)
> at
> java.util.jar.JarFile.getManifestFromReference(JarFile.java:160)
> at java.util.jar.JarFile.getManifest(JarFile.java:146)
>
> I believe this is happening because of the dot ('.', or period) in the name.
> If I use
> gmaven-runtime-default, this does not happen. If set <addExtensions/
> > to "false", it also does not happen. So this is fairly easy to
> work around, but it is also pretty difficult to troubleshoot unless
> you know where to look.
>
> Note that the code in the stack trace isn't mine. This is happening
> in Java, before my code ever gets called.
>
> This one is pretty hard to produce at random, though it is
> repeatable. You have to be running compiled Groovy from within a
> JAR where you have set up the MANIFEST with extensions on.
>
> One suggestion would be to call the artifact gmaven-runtime and set
> the version to 1.5, 1.6, whatever - the version of Groovy, plus
> maybe a point version and RC status. That would work, and it would
> not break the Java jarring mechanism.
