Hi,

Following the instructions here
https://bazel.build/install/compile-source#bootstrap-bazel

I retrieved bazel-8.2.1-dist.zip and extracted it to /root/bazel

Then cd /root/bazel

But got an error:

root@anvil:~/bazel# env EXTRA_BAZEL_ARGS="--tool_java_runtime_version=local_jdk" bash ./compile.sh

What did I do wrong/what can I do to get the build to succeed

Hi again!

Sorry to bother anyone, but I seem to have figured it out:

In the Bazel folder, I executed

chmod +x src/zip_builtins.sh

And now the build is proceeding.

Thank you
