+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or

+       of the following places: within a NOTICE text file distributed
+       as part of the Derivative Works; within the Source form or
+       documentation, if provided along with the Derivative Works; or,
+       within a display generated by the Derivative Works, if and
+       wherever such third-party notices normally appear. The contents
+       of the NOTICE file are for informational purposes only and
+       do not modify the License. You may add Your own attribution
+       notices within Derivative Works that You distribute, alongside
+       or as an addendum to the NOTICE text from the Work, provided
+       that such additional attribution notices cannot be construed
+       as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,

+   Notwithstanding the above, nothing herein shall supersede or modify
+   the terms of any separate license agreement you may have executed
+   with Licensor regarding such Contributions.
+
+6. Trademarks. This License does not grant permission to use the trade
+   names, trademarks, service marks, or product names of the Licensor,
+   except as required for reasonable and customary use in describing the
+   origin of the Work and reproducing the content of the NOTICE file.

+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions
+   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,

+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,

+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.
+
+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+Gerrit Scala Provider Plugin
+=============================
+
+This plugin provides Scala runtime environment for Gerrit plugins in Scala.
+
+To test this series must be applied on top of Gerrit master [1].
+
+To build link this directory under Gerrit's tree plugins directory and run:
+
+```
+  buck build plugins/scala-provider:scala-provider
+```
+
+The resulting artifact can be found under:
+
+```
+ buck-out/gen/plugins/scala-provider/scala-provider.jar
+```
+
+A sample Scala hello world script is:
+```
+  import com.google.gerrit.sshd._
+  import com.google.gerrit.extensions.annotations._
+
+  @Export("scala")
+  class ScalaCommand extends SshCommand {
+    override def run = stdout println "Hello from Scala!"
+  }
+```
+
+Copy and past the above sample Scala fragment into the file $GERRIT_SITE/plugin/hello-1.0.scala.
+
+The "hello" plugin version 1.0 will be automatically loaded into Gerrit and will provide a new
+SSH command "hello scala".

+Gerrit Scala Provider Plugin.
+
+This plugin provides Scala runtime environment for Gerrit plugins in Scala.
+Scala language level and library is Ver. 2.11.0 and does not require any
+external installation as everything is provided by this plugin as embedded
+engine.
+
+To test this series must be applied on top of Gerrit master [1].
+
+To test deploy the review plugin [2] and copy this Scala Provider plugin
+under `$gerrit_site/plugins` directory.

+Build
+=====
+
+This plugin is built with Buck.
+
+Clone or link this plugin to the plugins directory of Gerrit's source
+tree, and issue the command:
+
+```
+  buck build plugins/scala-provider
+```
+
+The output is created in
+
+```
+  buck-out/gen/plugins/scala-provider/scala-provider.jar
+```
+
+This project can be imported into the Eclipse IDE:
+
+```
+  ./tools/eclipse/project.py
