   > Please use https://repo1.maven.org/maven2/org/openlabtesting/protobuf/protoc/2.5.0/ for the aarch64 protoc binary,
   
   I've tried it before choosing os72 but it didn't work because:
   
   1) ${user.home}/.m2/repository/org/openlabtesting/protobuf/protoc/${protobuf-java.version}/protoc-${protobuf-java.version}-${os.detected.classifier}.exe has no executable bit 
   ```
   Caused by: java.io.IOException: Cannot run program "/home/ubuntu/.m2/repository/org/openlabtesting/protobuf/protoc/2.5.0/protoc-2.5.0-linux-aarch_64.exe": error=13, Permission denied

       ...
   ```
   
   2) After "chmod +x ..." it started failing with:
   ```

   ```
   i.e. the executable is dynamically linked
   ```
   file  /home/ubuntu/.m2/repository/org/openlabtesting/protobuf/protoc/2.5.0/protoc-2.5.0-linux-aarch_64.exe
   /home/ubuntu/.m2/repository/org/openlabtesting/protobuf/protoc/2.5.0/protoc-2.5.0-linux-aarch_64.exe: ELF 64-bit LSB shared object, ARM aarch64, version 1 (SYSV), dynamically linked, interpreter /lib/ld-linux-aarch64.so.1, for GNU/Linux 3.7.0, BuildID[sha1]=ad7c0941f0121611ef1963de1bf6d699e2517c5f, with debug_info, not stripped
   ```
   and nothing provides `libprotoc.so.8` in the LD_LIBRARY_PATH.
   
   I will contact the OpenLab Testing guys and see whether they can release 2.5.0.1 with statically linked executable!
