How about having multiple repos?

    </repository>
    <repository>
        <id>ibm-jars-bundle-lv1</id>
        <url>file://${basedir}/../ibm-jars-bundle/repo</url>
    </repository>
    <repository>
        <id>ibm-jars-bundle-lv2</id>
        <url>file://${basedir}/../../ibm-jars-bundle/repo</url>

Answer 2

Although it is annoying in your case, this is well-known and intentional. A maven project should know about its execution directory only, no matter in what context it is executed.

I asked almost the same question: Maven variable for reactor root earlier, and the only answer that made sense was to use ${user.dir}, although it's hacky and will not work if you build from a module directory.

(There is also this very verbose solution: Maven2 property that indicates the parent directory)
