How to speed up the signing of the bank?

Question

I use ant to sign my banners to deploy web start. Ant.signjar is very slow when subscribing to a web start. How to speed up the signing process?

Answer 1

I found one possible solution.

Earlier in the build script, ant.signjar was called sequentially for all cans (we use gradle to build, more than 20 MB of dependencies). Now I use the methods for the groovy library: withPool (4) and eachParallel {ant.signjar}. This is great for 2 cores in my computer and 4 cores in the build server. (3 times faster)

The second trick is the cache: we use cached signed banks for all RELEASE / NON-SNAPSHOT dependencies. When we run the assembly without cleaning it works faster because it uses cached signed libraries from the assembly directory.

Answer 2

I usually use 2 goals: one to sign the entire project, and the other to sign my cans. Thus, the latter will not rewrite dependencies and make the signing process much faster.
