-Build
-=====
-
-This plugin is built with Bazel and two build modes are supported:
-
-* Standalone
-* In Gerrit tree.
-
-Standalone build mode is recommended, as this mode doesn't require local Gerrit
-tree to exist.
-
-## Build standalone
-
-To build the plugin, issue the following command:
-
-```
-  bazel build @PLUGIN@
-```
-
-The output is created in
-
-```
-  bazel-genfiles/@PLUGIN@.jar
-```
-
-To package the plugin sources run:
-
-```
-  bazel build lib@PLUGIN@__plugin-src.jar
-```
-
-The output is created in:
-
-```
-  bazel-bin/lib@PLUGIN@__plugin-src.jar
-```
-
-To execute the tests run:
-
-```
-  bazel test //...
-```
-
-This project can be imported into the Eclipse IDE. Execute:
-
-```
-  ./tools/eclipse/project.sh
-```
-
-to generate the required files and then import the project.
-
-
-## Build in Gerrit tree
-
-Clone or link this plugin to the plugins directory of Gerrit's source
-tree, and issue the command:
-
-```
-  bazel build plugins/@PLUGIN@
-```
-
-The output is created in
-
-```
-  bazel-genfiles/plugins/@PLUGIN@/@PLUGIN@.jar
-```
-
-To execute the tests run:
-
-```
-  bazel test plugins/@PLUGIN@:delete_project_tests
-```
-
-or filtering using the comma separated tags:
-
-````
-  bazel test --test_tag_filters=@PLUGIN@ //...
-````
-
-This project can be imported into the Eclipse IDE.
-Add the plugin name to the `CUSTOM_PLUGINS` set in
-Gerrit core in `tools/bzl/plugins.bzl`, and execute:
-
-```
-  ./tools/eclipse/project.py
-```
