Gradle Plugin for Freeplane Script and Add-on Development

The plugin allows easy debugging of Freeplane groovy scripts in IDE and adds tasks packageAddon and prepareAddonSource to package your scripts as Freeplane add-on. The packaging requires Freeplane with installed Developer Tools Add-on (see https://www.freeplane.org/wiki/index.php/Add-ons_(install)#Developer_Tools).

On MacOS gradle should run under JAVA 8 for executing packageAddon. Otherwise you can run prepareAddonSource and open with build/addon/yourFile.mm in Freeplane and package it manually. On other OS all JAVA versions are supported.

Usage

Directory structure:

Put your source code to be packaged as jar file under

• src/main/groovy
• src/main/java
• src/main/resources

Put your scripts under

• src/scripts/groovy

Add your dependencies either to special configuration addon to be included in the created add-on installer.

Put your add-on definition mind map and add-on resources not packaged in add-on jar into

• /src/addon

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'org.freeplane:gradle-freeplane-plugin:0.8'
    }
}

repositories {
    mavenCentral()
}

apply plugin: 'org.freeplane.gradle-freeplane-plugin'

java {
    toolchain {
        languageVersion = JavaLanguageVersion.of(8)
    }
}

freeplane {
    // mandatory, freeplane installation directory.
    // (Freeplane.app directory on MacOS)
    // In this example it is taken from system environment.
    freeplaneDirectory = System.env.FREEPLANE_DIR

    // recommended, freeplane user setting directory. 
    // It should be specified without the version number suffix.
    // The value used by default can be different from your OS default.
    // userDirectory = 'user-directory'

    // optional, addon source directory
    // addonSourceDirectory = 'src/addon'

    // optional, to be set only if more then one mind map file in the addon source directory
    // addonDefinitionMindMapFileName = 'Greetings.mm'

    // optional, includes
    // includes = ['**/*']

    // optional, excludes
    // excludes = ['**/*.bak', '**/~*', '**/$~*.mm~', '**/*.gdsl', '**/*.dsld']

    // optional, max heap size for freeplane
    // maxHeapSize = '1024m'

    // optional, additional Java Runtime options
    // jvmArgs = []

}

jar {
    archiveFileName = 'greetings.jar'
}

Debugging

For debugging

• import gradle project and freeplane gradle project into your IDE (See related freeplane wiki page)
• Let IDE compile the addon project
• run Freeplane in IDE debugger

In Freeplane Tools -> Preferences -> Plugins

• add all source script directories to Script search path in Freeplane preferences
• add class root directories compiled by IDE to Script classpath in Freeplane preferences

Restart freeplane and you should be able to debug your scripts and library source files.

Example add-on project

There is an example add-on project greetings available in folder examples of this repository.
