You missed:

  2. git clone --recursive https://gerrit.googlesource.com/gerrit

3. cannot build any Gerri plugin

I think the reason for that failure was also explained in this comment [1].

I'd like to add that one should not run this in a Gerrit site directory¹, but instead on your workstation or similar. Then transfer the build (.jar) to your site in the plugins/ folder.

I read the following documentation https://github.com/GerritCodeReview/gerrit/blob/master/README.md, however I still have issues building Gerrit tree

Please could you see the following bazel command output https://bugs.chromium.org/p/gerrit/issues/attachmentText?aid=352855

The things that I've tried

1. Change to another commit unsuccessfully
2. remove manually every time that the command output shonw me a package in Gerrit tree, e.g : ./lib/js/bower_components.bz, the thing is that every time after run the command it shows me a different one.


even with that I tried to build non-core plugins and the only ones that I've build successfully are:

Are you building behind a proxy? I've found that when building Gerrit (or plugins) using bazel, I need to change my https proxy environment variable a bit:

echo $HTTPS_PROXY
https://...
echo $HTTP_PROXY
http://...
export HTTPS_PROXY=$HTTP_PROXY

I get the same "no such package '@iron-form-element-behavior//'" error when building Gerrit

with my HTTPS_PROXY set to https://, but when I change it to http:// it magically is able to find dependencies.

I don't entirely remember why that fixed it for me (lots of googling was involved), but it's worth a try if you're working behind a proxy.

I can successfully build current vanilla gerrit master with bazel

That's not enough, as this document doesn't tell you what

pre-requisites are required to build Gerrit core and plugins.

You have to follow this document: [1], that references yet

another document: [2] with more requirements, related to

new and shiny Gerrit UI.
