>
> In the environment I work in, we have a Maven project that uses the XMLBeans
> plugin to 'compile' over 1,300 schema files. The jar file that's generated
> by the JAR plugin contains well over 167,000 individual entries. While it is
> a 'valid' jar file, the tremendous number of entries in that file are causing
> some obscure runtime errors. We have determined that the number of entries
> in the jar file is the cause of these errors because the errors do not occur
> if we manually break up that one massive jar file into several smaller jar
> files.
> The attached patch file contains updates to the maven-jar-plugin that provide
> this jar-splitting capability within the Maven build environment. This patch
> basically adds a new parameter (jarFileCount) to the JarMojo. If that
> parameter is 1 or less, then the existing jar-creation logic is used.
> However, if that parameter is greater than 1, then multiple jar files are
> created, each with about the same number of files in them. The classifier is
> used to differentiate the various jar files that are crated when the
> jarFileCount parameter is greater than one. The sizes of these smaller jar
> files may vary greatly, but the number of files in them will be relatively
> consistent.
> The attached patch also contains several integration tests which exercise
> this new capability.
