I just compiled Axoloti for the first time in a few months on an Arm-based Linux box with 4GB RAM.
Compiling the patcher itself was very quick, but the it spent two hours(!!) building the javadoc tree. Is there anyway to turn that bit off? I looked at build.xml but I don't know ant.
I think that should work, at least for incremental builds.
or if you want to remove it 'permanently', you can add the following to the build.xml fie
this tells ant to do nothing for javadoc
