Simple utility that splits a large jar file into one or more jar
files that are each less than the file size specified with
--max_file_size.
This class strips out jar index files. It does not, however,
ensure that resource or META-INF files are directed to the
appropriate jar file. It's unclear whether this will cause
problems or not.
UPDATE to the lack of clarity: It is now clear that this will
cause problems. Some frameworks (datanucleus in particular)
make assumptions about the colocation of well-known files
and the manifest in the same jar. Splitting the jar
violates these assumptions.
Usage:
JarSplitter --input_jar=MyProject_deploy.jar \
--output_directory=./lib \
--max_file_size=10000000 \
--replicate_manifests=false \
--exclude_suffixes=.so,.dll
