WARNING

This fork was hacked to support the latest closure compiler. Well, almost the latest, as supporting the latest looks difficult because v20200920 and onwards started using jarjar and that's incompatible with PlovrCompilerOptions.java. As it is now, the code does not pass some of its own tests because they are brittle and I'm not going to spend time fixing them. I'm only touching this because I need it to build something else.

Plovr: A Closure build tool

plovr is a build tool that dynamically recompiles JavaScript and Closure Template code. It is designed to simplify Closure development, and to make it more enjoyable.

Using Plovr

Plovr requires Java 7 or higher.

Downloading Plovr

You can find Plovr JARs for download on the Releases page

Building Plovr from Source

The Plovr build requires the Java Development Kit (JDK) 7 or higher, Buck, and zip.

When following the Buck installation instructions, double-check that you are following the instructions for building Java projects and for your operating system. If you have trouble installing Buck (which can be non-trivial on Windows), please contact the Buck team.

To test:

buck fetch ...
buck test

To build:

buck fetch ...
buck build plovr

The output of the build will be in buck-out/gen/plovr.jar.

Building Plovr inside a Docker container

If you want to build plovr without installing Buck on your local machine, we have a Docker container with Buck installed.

The Plovr build is split into two Dockerfiles:

• Dockerfile builds and tests Plovr
• Dockerfile.base builds Buck and Plovr's dependencies

To test:

docker build .

downloads the plovr-deps container from docker, adds Plovr source, and runs all the Plovr tests.

If you want to build plovr-deps yourself:

docker build -t nicks/plovr-deps -f Dockerfile.base .

To Upgrade Closure Library

To upgrade one of Closure Library, go to the official repo and find the SHA digest of the commit you want to sync to. Then run.

scripts/update-closure-library.sh sha-digest

Sometimes this doesn't work because git subtree is buggy. If nothing updates, try running:

scripts/update-closure-library.sh master
git reset --hard origin/master
scripts/update-closure-library.sh sha-digest

This will bully git subtree into shape.

To Upgrade Closure Compiler, Closure Templates, or Closure Spreadsheets

The Closure Compiler, Template, and Spreadsheets depenencies are managed with Maven.

Follow the instructions in third-party/README.md.
