I'm trying to get an executable JAR that contains groovy code that I

repo.
sourceCompatibility = '1.6'

repositories {
// Use local Maven repo location. We don't need this if we only

mavenRepo urls: localMavenRepo
}
// Project configuration:
version = '1.0-SNAPSHOT'
group = 'org.mindscratch.foo'
// The following line is not necessary. Default the install tasks
depends on the

install.dependsOn ':build'
repositories {
mavenCentral() // Define Maven central repository to look for
dependencies.
}
dependencies {
groovy 'org.codehaus.groovy:groovy:1.6.7' // group:name:version
is a nice shortcut notation for dependencies.
testCompile 'junit:junit:4.7'
}
task initProject(description: 'Initialize project directory
structure.') << {
// Default package to be created in each src dir.
def defaultPackage = 'org/mindscratch/foo'
['java', 'groovy', 'resources'].each {
// convention.sourceSets contains the directory structure
// for our Groovy project. So we use this struture
// and make a directory for each node.
convention.sourceSets.all."${it}".srcDirs*.each { dir ->
def newDir = new File(dir, defaultPackage)
logger.info <http://logger.info> "Creating directory $newDir" //
gradle -i shows this message.
newDir.mkdirs() // Create dir.
}
}
}
I run:
$ gradle install -i
$ cd build/libs
$ java -jar foo-1.0-SNAPSHOT.jar
..doesn't work b/c the Groovy jar isn't on the classpath (or inside my
JAR). GUess what I need is a JAR that contians the Groovy jar inside
of it (maybe in a "lib" folder). Can you help?
The cookbook has some options for creating a JAR which contains its
compile or runtime dependencies:
http://docs.codehaus.org/display/GRADLE/Cookbook#Cookbook-Creatingafatjar
There's also a JIRA issue for making this easier:
