Optimizing Intellij Build Time with Ant



With a decently powerful machine, building Intellij CE using ant takes about 35 minutes. I know this is far from what is possible and I intend to increase the heap size and try arrange compiling of independent modules in parallel, outside of Intellij (builds will be run on a remote build server). Just wondering if you guys have any quick tips on how I can make the ant build time faster, without using the Intellij IDE?

Any tips would be appreciated.

Invest into fast SSDs, lots of memory, as many CPU cores as possible :)

Other than that, these build times are kinda expected.
