MPS Maven Deployer

A Gradle script to automate the deployment of JetBrains MPS into a Maven repository (either local or remote).

Usage

Clone maven-mps-deployer.
In the root directory of the project run the following command:
```
./gradlew publishToMavenLocal -PmpsVersion=<MPS version>
```
where <MPS version> is a two- or three-component version number, such as 3.4 or 3.4.1. If you want to deploy MPS artifacts to a non-local Maven repository, run gradlew publish:
```
./gradlew publish
    -PmpsVersion=<MPS version>
    -PrepositoryUrl=http://myrepo
    -PrepositoryUsername=joe
    -PrepositoryPassword=secret
```

(all on one line). The repositoryUsername and repositoryPassword parameters are optional.

Deployed Artifacts

The deployer downloads the official MPS distribution in zip format from JetBrains and repackages it into two artifacts. Both artifacts have groupId of org.jetbrains.mps so you can find them under $HOME/.m2/repository/org/jetbrains/mps in the local repository after deployment.

org.jetbrains.mps:mps: the whole MPS archive is repackaged to include the contents of its top-level directory directly into the archive.

For example, the MPS-3.4.1.zip as downloaded from JetBrains contains a top-level directory named MPS 3.4 which contains MPS files and directories (such as lib, plugins, or languages). Having the top-level directory with a version-dependent name is impractical for automation, so a new archive is created to include the MPS 3.4 directory contents (the above mentioned lib, plugins, languages, etc.) directly.

The structure of this artifact is stable and should not change unless MPS packaging changes drastically.
org.jetbrains.mps:mps-libs: certain MPS libraries are packaged together into mps-libs.jar. This artifact is intended for internal use by mps-maven-plugin only. Specifically, it provides MPS API for (a part of) mps-maven-plugin. This artifact is not required to run the plugin since at runtime the plugin uses the JARs from org.jetbrains.mps:mps. As such, the artifact's internal structure may change and it may even be removed at some point.
