Maven update manifest in dependency jars - maven

Question

Webstart requires that all jar files has certain manifest entries, so now I have to go through all dependencies and update each manifest. Is there a way to get maven update manifest files in arbitrary jar files?
Ideally I would like:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<version>2.2</version>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>target</outputDirectory>
<!-- something like this -->
<manifestEntries>
<Trusted-Library>true</Trusted-Library> <!-- does not work! -->
</manifestEntries>
</configuration>
</execution>
</executions>
</plugin>

Answer 1

Are you sure that every jar need to contains MANIFEST? I think it's needed only in Jar with your entry / main class. You can generate it using maven-jar-plugin:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<addMavenDescriptor>true</addMavenDescriptor>
<manifestEntries>
<Permissions>all-permissions</Permissions>
<Application-Name>Your Application name</Application-Name>
</manifestEntries>
<manifest>
<mainClass>${entry.class}</mainClass>
</manifest>
</archive>
<finalName>${project.artifactId}</finalName>
</configuration>
</plugin>

You could use Webstart Maven Plugin:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>webstart-maven-plugin</artifactId>
<version>1.0-beta-6</version>
<dependencies>
<dependency>
<groupId>org.codehaus.mojo</groupId>
<artifactId>keytool-api-1.7</artifactId>
<version>1.5</version>
</dependency>
</dependencies>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>jnlp-inline</goal>
</goals>
</execution>
</executions>
<configuration>
<filenameMapping>simple</filenameMapping>
<versionEnabled>false</versionEnabled>
<jnlpFiles>
<jnlpFile>
<templateFilename>default-jnlp-servlet-template.vm</templateFilename>
<outputFilename>yourJnlp.jnlp</outputFilename>
<jarResources>
<jarResource>
<groupId>your.package</groupId>
<artifactId>ArtifactId</artifactId>
<version>${project.version}</version>
<mainClass>your.main.Class</mainClass>
</jarResource>
</jarResources>
</jnlpFile>
</jnlpFiles>
<unsignAlreadySignedJars>true</unsignAlreadySignedJars>
<canUnsign>true</canUnsign>
<libPath>lib</libPath>
<codebase>$$$codebase</codebase>
<updateManifestEntries>
<Caller-Allowable-Codebase>*</Caller-Allowable-Codebase>
<Trusted-Library>true</Trusted-Library>
<Application-Library-Allowable-Codebase>*</Application-Library-Allowable-Codebase>
<Application-Name>ApplicationName</Application-Name>
<Permissions>all-permissions</Permissions>
<Codebase>*</Codebase>
<Trusted-Only>true</Trusted-Only>
</updateManifestEntries>
<jnlp>
<j2seVersion>1.7+</j2seVersion>
<outputFile>your_jnlp.jnlp</outputFile>
<mainClass>your.class.here</mainClass>
</jnlp>
<sign>
<keystore>${project.basedir}/youekeystore</keystore>
<storepass>...</storepass>
<alias>your_alias</alias>
<verify>false</verify>
</sign>
<verbose>true</verbose>
</configuration>
</plugin>
