Lintian reports missing-classpath problem for libswirl-java
http://lintian.debian.org/maintainer/[email protected]#libswirl-java
http://lintian.debian.org/tags/missing-classpath.html
"None of the jar files contained in the package declare a Class-Path in
their manifest, but the package depends on at least one java library.
That means that either the dependency is not needed or at least one of
the JARs should include a classpath..."
This s due to ANT building the JAR file with default contents of
$ unzip -qc swirl.jar META-INF/MANIFEST.MF
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.2
Created-By: 1.6.0_24-b24 (Sun Microsystems Inc.)
>From Lintian point of view, it expects (debian/control)
Package: libswirl-java
Depends: ${misc:Depends}, libjdom1-java
thus requiring the manifest to read:
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.8.2
Created-By: 1.6.0_24-b24 (Sun Microsystems Inc.)
+ Class-Patch: /usr/share/java/jdom1.jar
SOLUTION
There is no easy way to manipulate auto-generated manifest files. Therefore
a script:
dh_javajarmanifest
would help to deal with JARs and make them Debian compliant.
IMPLEMENTATION
Program dh_javajar would read debian/<package>.jarmanifest file whose
syntax would be
<command> <string>
Where commands would be:
new Add new header to the end, or replace existing header
del Delete header, or do nothing if no header exists
An example (for the USE CASE):
# debian/libswirl-java.jarmanifest
new Class-Path: /usr/share/java/jdom1.jar
