How to set the JDK target used into MANIFEST.MF Build-Jdk

[Dobri Kitipov]

Hi all,
currently I am trying to set properly the JDK target used when jarring my
modules. What I have tried is:

            <build>
                <plugins>
                    <!-- maven2 jar plugin configuration -->
                    <plugin>
                        <groupId>org.apache.maven.plugins</groupId>
                        <artifactId>maven-jar-plugin</artifactId>

                        <configuration>
                            <archive>
                                <!-- do not include maven artifacts in the
generated archives -->

<addMavenDescriptor>false</addMavenDescriptor>
                                <!-- add the follwoing entries to the
default MANIFEST.MF file -->
                                <manifestEntries>
                                    <Build-Jdk>test
${maven.compiler.compilerVersion}
${maven.compiler.target}</Build-Jdk><!--${maven.compiler.compilerVersion}-->
                                </manifestEntries>
                            </archive>
                        </configuration>
                    </plugin>
..........................

The problem seems to be that ${maven.compiler.compilerVersion} has not been
initialised yet neither the ${maven.compiler.target} expression, when it
should be set into the <Build-Jdk> entry. When I open the MANIFEST.MF I see
that Build-Jdk is set to "test null".

I have read a JIRA related to this issue:
[jira] Created: (MPJAR-49) Incorrect jdk version in "Build JDK" in manifest
when maven.compile.executable is set
but it seems I can not fix it.

Could you advise me.

Thank you
Dobri
