-Build
-=====
-
-This plugin can be built with Buck or Maven.
-
-Buck
-----
-
-Two build modes are supported: Standalone and in Gerrit tree.
-The standalone build mode is recommended, as this mode doesn't require
-the Gerrit tree to exist locally.
-
-
-
-Clone bucklets library:
-
-```
-  git clone https://gerrit.googlesource.com/bucklets
-
-```
-and link it to @PLUGIN@ plugin directory:
-
-```
-  cd @PLUGIN@ && ln -s ../bucklets .
-```
-
-Add link to the .buckversion file:
-
-```
-  cd @PLUGIN@ && ln -s bucklets/buckversion .buckversion
-```
-
-To build the plugin, issue the following command:
-
-
-```
-  buck build plugin
-```
-
-The output is created in
-
-```
-  buck-out/gen/@PLUGIN@.jar
-```
-
-
-Clone or link this plugin to the plugins directory of Gerrit's source
-tree, and issue the command:
-
-```
-  buck build plugins/@PLUGIN@
-```
-
-The output is created in
-
-```
-  buck-out/gen/plugins/@PLUGIN@/@PLUGIN@.jar
-```
-
-This project can be imported into the Eclipse IDE:
-
-```
-  ./tools/eclipse/project.py
-```
-
-Maven
------
-
-Note that the Maven build is provided for compatibility reasons, but
-it is considered to be deprecated and will be removed in a future
-version of this plugin.
-
-To build with Maven, run
-
-```
-mvn clean package
-```
