Bazel - unable to build with Android Studio

Question

First, I installed and configured Bazel, now I am able to succesfully compile and deploy app, using that tutorial.

However, I'm stuck with Android Studio. I installed official Bazel plugin, then tried to import my Bazel project to Android studio (import from BUILD file). And I'm getting sync errors:

Syncing project: Sync (incremental)... Updating VCS... Running Bazel info... Command: bazel info --tool_tag=ijwb:AndroidStudio --curses=no --color=yes --progress_in_terminal_title=no --

Computing VCS working set... Querying targets in project directories... Command: bazel query --tool_tag=ijwb:AndroidStudio --output=label_kind --keep_going "attr(\"tags\", \"^((?!manual).)*$\", //src/main/...:all)" --

2 targets found under project directories; syncing 2 of them. Sync targets from project view directories:
//src/main/java/com/example/bazel:greeter_activity //src/main:app

Answer 1

You need to clean by `bazel clean --expunge`. It will remove all downloaded artifacts. You should clean and rebuild by below steps. 

1. Please uncheck 'Bazel > Sync > Expand Sync to Working Set' and try again.
2. Build through bazel plugin from intellij

Answer 2

The pile of error messages here is hard to read, but here's the root cause:

"/home/michal/.cache/bazel/_bazel_michal/d2759e71c9e0462cf95e741761af2e78/external/intellij_aspect/intellij_info_impl.bzl", line 118, in get_res_artifacts for file in resource.files: ... type 'depset' is not iterable. Use the to_list() method to get a list. Use --incompatible_depset_is_not_iterable=false to temporarily disable this check.

Either add build --incompatible_depset_is_not_iterable=false to your project's .bazelrc file, or wait for the next plugin release v2019.09.16 that contains the patch fix.
