Adds tasks to Gradle projects which help in compiling, assembling, and packaging extensions to Alfresco, particularly those deployed as Alfresco AMP projects.


The project currently requires that Gradle and Maven be installed.

Building this Project

To build this plugins project and install in your local maven repo run:

cd alfresco-gradle-plugins
gradle install

Adding the Plugins to Your Project

  1. Create a lib-compile directory in your project
  2. Add the alfresco-gradle-plugins jar to lib-compile
  3. In the build.gradle file of your project add:

    buildscript {
        dependencies {
            classpath fileTree(dir: 'lib-compile', include: '**/*.jar')
    buildscript {
       configurations.classpath.resolutionStrategy.cacheChangingModulesFor 0, 'seconds'
  4. Add each plugin you want to use:

    // apply plugin: 'alfresco-war-dependencies'   // optional
    apply plugin: 'amp'

You could instead checkout the alfresco-gradle-plugins source and run gradle install to build and install in your local Maven repository then declare a dependency on that artifact.

Task: amp

The amp task (available in the amp plugin) packages an Alfresco AMP for deployment via the Module Management Tool.

Running the amp Task

To compile and package run the following from your AMP project:

cd *my-amp-project*
gradle amp

The packed AMP will be available at build/distributions/*moduleId*-*version*.amp of each subproject by default.

Subprojects Layout

For each subproject the standard Gradle Java plugin project layout is assumed with the addition of a source config dir, .i.e. src/main/config.

Note that files in your resources directory are placed into the compiled jar while files in the config directory are placed in the config dir of the AMP. is used as your AMP module id by default.

You can override these properties in


Property name Type Default value Description
moduleId String The AMP module id
alfrescoVersion String 4.0.d The version of Alfresco to use for dependencies
alfrescoEdition String community The edition of Alfresco to use for dependencies, community or enterprise
sourceConfigDir String src/main/config The source directory for configuration files
sourceConfigModuleDir String sourceConfigDir/alfresco/module/moduleId The source directory for AMP module-specific configuration files
sourceWebDir String src/main/web The source directory for web files such as JSP, CSS, and JavaScript files
dependencyLibsDir String lib Directory containing jar files that should be copied into the AMP for deployment
licensesDir String licenses Directory containing license files that should be copied into the AMP for deployment
fromMavenArchetype Boolean false Whether or not this project was create from the Alfresco Maven archetypes

The plugin also uses many of the convention properties from the Java plugin.

Dependencies Management

The amp plugin automatically adds the follow dependencies to your project:

  • "compile", "org.alfresco:alfresco-repository:${project.alfrescoVersion}"
  • "compile", "org.alfresco:alfresco-core:${project.alfrescoVersion}"
  • "compile", "org.alfresco:alfresco-data-model:${project.alfrescoVersion}"
  • "compile", "org.springframework:spring-core:${project.springVersion}"
  • "compile", "org.springframework:spring-beans:${project.springVersion}"
  • "compile", "org.springframework:spring-context:${project.springVersion}"
  • "compile", project.fileTree(dir: 'lib', include: '*/.jar')
  • "testCompile", "junit:junit:4.+"

If your project needs additional dependencies for compiling or testing add them in a dependencies block under subprojects in build.gradle.

If your AMP needs to include jars which are specified via Maven dependencies you can simply add them to the 'ampLib' dependency configuration and the amp task will copy them to the final AMP archive, i.e.:

dependencies {
    ampLib group: 'com.example', name: 'some-artifact', version: '1.0-SNAPSHOT'

Note that transitive dependencies are not included for modules declared in the 'ampLib' configuration.

Overlaying AMP Config and Web Sources

There may be instances where you want a core set of functionality in your share and repo AMPs but want to override or extend portions of the config or web directories for certain deployments.

In this case you can overlay another source set by adding to the ampConfig, ampConfigModule, and ampWeb configurations. For example, in addition to src/main/config/ you might have src/client1/config and src/client2/config, so in your build.gradle file you might have something like:

if (project.hasProperty('overrideSource')) {
    dependencies.add('ampConfig',  files("src/${project.overrideSource}/config"))
    dependencies.add('ampConfigModule', files("src/${project.overrideSource}/config/alfresco/module/${moduleId}"))
    dependencies.add('ampWeb', files("src/${project.overrideSource}/web"))

then when to create the AMPs specific to client1 you'd run:

gradle amp -PoverrideSource=client1

Coming From Maven Archetypes

If your project was created by the Alfresco Maven archetypes you can set fromMavenArchetype to true in your file and maintain the same project structure and files you've used before. The archetype's file mapping during assembly of the AMP (i.e. src/main/config/context -> config/alfresco/module/*moduleId* within the AMP) will be maintined and velocity template paramters will also be expanded within your and module-context.xml files.

Related Tasks

Task Description
setBuildNumberFromSvnRevision Uses Subversion to set project.buildNumber to the last revision if available, otherwise zero
assembleAmp Does the work of assembling the AMP structure but does not zip into a deployable .amp file
compressAmp Applies YUI compressor to JS and CSS files within the assembled AMP structure

Task: installAmp

The installAmp task (available in the amp plugin) assembles and packages your AMP then uses Alfresco's MMT code to install it into the WAR set in the warFile property and can be specified on the command line:

gradle installAmp -PwarFile=/Path/To/WAR/File

Note that this should be run from subprojects or both share and repo AMPs will be applied to the specified warFile.

Task: installDevelopmentAmp

The installDevelopmentAmp task (available in the amp plugin) copies the files in your AMP project directly into a specified exploded WAR for development purposes only. The changes can not be revoked, and no directives are followed.

The path to the exploded WAR is set in the warExplodedDir property and can be specified on the command line:

gradle installDevelopmentAmp -PwarExplodedDir=/Path/To/Exploded/WAR

Note that this should be run from subprojects or both share and repo AMP structure will be applied to the specified warExplodedDir.

Example Project

Checkout the alfresco-gradle-amp-example project for an example on how to use the Gradle amp plugin.

Other Tasks


You can upload the alfresco-gradle-plugins artifact to a maven repository by specifying:

  • mavenUploadRepository
  • mavenUsername
  • mavenPassword

as properties for your project and running the upload task (available in the amp plugin). Note that you'll probably not want to store your username and password in clear text so you can specify those via command line:

gradle clean upload -PmavenUsername=myUsername -PmavenPassword=myPassword


You can also upload the alfresco-gradle-plugins artifact to a maven repository using the maven command line by specifying:

  • mavenUploadRepositoryId
  • mavenUploadRepository

as properties for your project and setting up your mvn repositories, including encrypted passwords, then run:

gradle clean uploadArchivesViaMvn

(available in the amp plugin)


The explodeWarDependencies task (available in the alfresco-war-dependencies plugin) extracts the jars and configs from the WAR file specified in warFile to be used as dependencies in the project.
A compile dependency on all jars in dependenciesExplodedLibsDir is also added to the project.

Running the explodeWarDependencies Task

To extract the configs and jars from warFile place the WAR in the root of your project and run the following:

cd *my-amp-project*
gradle explodeWarDependencies

By default the task is looking for alfresco.war and the extracted files will be available at explodedDependencies. You can override these defaults in


Property name Type Default value Description
warFile String alfresco.war The path to the WAR file that should be used as a dependencies source
dependenciesExplodedDir String explodedDependencies The path to the directory where the extracted dependencies should be placed
dependenciesExplodedLibsDir String dependenciesExplodedDir/lib The path to the directory where the extracted jars should be placed
dependenciesExplodedConfigDir String dependenciesExplodedDir/config The path to the directory where the extracted configuration files should be placed
