http://nagoya.apache.org/bugzilla/show_bug.cgi?id=16972 Jar task incorrectly builds INDEX.LIST entries. Summary: Jar task incorrectly builds INDEX.LIST entries. Product: Ant Version: 1.5.1 Platform: All OS/Version: All Status: NEW Severity: Normal Priority: Other Component: Core tasks AssignedTo: [EMAIL PROTECTED] ReportedBy: [EMAIL PROTECTED] The "META-INF/INDEX.LIST" file created by the core Jar task does not correctly index files with null package space names. As defined by the Jar spec (which you quote from on the Jar task's manual page), the INDEX.LIST file should simply list package directories instead of putting in a line for every class file (this reduces overhead). However, to quote: "Only for classes with null package name, and resource files which reside in the root directory, will the mapping be recorded at the individual file level." The Jar task currently does not provide for this exception; when building the INDEX.LIST file, the Jar task simply iterates over the "addedDirs" Hashtable from the Zip superclass and prints the directory names out to the index file. Thus, suppose the following directory structure: com/obs/test/TestClass.class resources/foo.xml resources/bar.gif root.xml baz.gif The correct INDEX.LIST file (as generated by `jar -i` would contain the entries: com com/obs com/obs/test resources root.xml baz.gif Whereas the Ant-generated Jar would contain only com com/obs com/obs/test resources (The root-level elements 'root.xml' and 'baz.gif' would be missing). As a temporary work-around, the following are possible: - Do not build indices for Jar files in Ant (set index="no") - Build indices manually with direct calls to Java's 'jar' tool (jar -i) - Place all resources in non-root level of Jar heirarchy I'm not submitting a patch, as I'm not sure how you wish to address the problem. Most likely, you'll need to create another hashtable of root elements, and add to it when you process a file with no directory prefix (line 789 of Zip.java in v1.5.1 looks like a cozy spot for that).
