-# Build
-
-This plugin can be 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. Moreover, there are some limitations and additional manual steps
-required when building in Gerrit tree mode (see corresponding sections).
-
-## Build standalone
-
-To build the plugin, issue the following command:
-
-```
-  bazel build @PLUGIN@
-```
-
-The output is created in
-
-```
-  bazel-bin/@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:
-
-```
-  ./tools/eclipse.sh
-```
-
-## Build in Gerrit tree
-
-Clone or link this plugin to the plugins directory of Gerrit's
-source tree. Put the external dependency Bazel build file into
-the Gerrit /plugins directory, replacing the existing empty one.
-
-```
-  cd gerrit/plugins
-  rm external_plugin_deps.bzl
-  ln -s @PLUGIN@/external_plugin_deps.bzl .
-```
-
-From Gerrit source tree issue the command:
-
-```
-  bazel build plugins/@PLUGIN@
-```
-
-The output is created in
-
-```
-  bazel-bin/plugins/@PLUGIN@/@PLUGIN@.jar
-```
-
-To execute the tests run either one of:
-
-```
-  bazel test --test_tag_filters=@PLUGIN@ //...
-  bazel test plugins/@PLUGIN@:@PLUGIN@_tests
-```
-
-This project can be imported into the Eclipse IDE:
-Add the plugin name to the `CUSTOM_PLUGINS` and to the
-`CUSTOM_PLUGINS_TEST_DEPS` set in Gerrit core in
-`tools/bzl/plugins.bzl`, and execute:
-
-```
-  ./tools/eclipse/project.py
-```
-
-How to build the Gerrit Plugin API is described in the [Gerrit
-documentation](../../../Documentation/dev-bazel.html#_extension_and_plugin_api_jar_files).
-
-[Back to @PLUGIN@ documentation index][index]
