The background is that I was trying to build Eclipse on riscv64. But from start, I was always stuck in failure like this. At first I thought this was raised by not build support on riscv64 for eclipse(in fact, there are much work needs to be done for Eclipse on riscv64 indeed), but with the development of supporting for riscv64, we have faced the issue again.

Thanks to akurtakov's help, so we have to look at JNA here.

Below is our found.

I downloaded the jna-5.14.0.jar to extra it and found

eclipse/mvn/com$ ls sun/jna/linux-riscv64/
libjnidispatch.so

But more odd is that as akurtakov said, we do not find there is no an entry about riscv64 in MANIFEST.MF. Did we do this on purpose? Personally I suspect the issue lead to the build failing on riscv64. Please correct me if I am wrong. TIA.
