IntelliJ has a post-build process to generate an index for things that can be searched in the UI. They perform this operation by running the IDE headless with a “traverseUI” argument. All these generated files are stored in searchable-options and we ensure its consistency via tests.
The test //tools/adt/idea/searchable-options:searchable_options_test ensures that the bundled xmls are up-to-date. If this test fails, its outputs.zip file contains the new .xmls that need to be updated.
Alternatively, running
bazel run //tools/adt/idea/searchable-options:update_searchable_options
Will build the studio bundle, and update the source files with the latest index.
