Gradle root project with multiple applications - gradle

Question

How do I create a gradle root project with multiple applications that use the same library. I'm wanting to end up with tar and zip files containing:
RootProject/
bin/
Command1
Command2
...
lib/
Library.jar
..
I created a gradle root project, the library sub-project, and several application sub-projects:
RootProject/
settings.gradle
build.gradle
common.gradle
Library/
build.gradle
src/main/java/Library.java
Command1/
build.gradle
src/main/java/Command1.java
Command2/
build.gradle
src/main/java/Command2.java
My current root project's build.gradle:
apply plugin: 'base' // To add "clean" task to the root project.
allprojects {
repositories {
mavenCentral();
}
}
subprojects {
apply plugin: 'java'
group = 'edu.csusb.ecs.gmailsettings'
version = '1.0-SNAPSHOT'
dependencies {
testCompile group: 'junit', name: 'junit', version: '4.10'
}
}
task build(type: Copy) {
dependsOn subprojects.build
from subprojects.collect { it.tasks.withType(Jar) }
into project.rootProject.buildDir.toString() + "/libs"
}
task clean(group:project.rootProject.ext.group, type: Delete, description:"clean jars from subprojects") {
delete fileTree(project.buildDir).include('**/*')
}
results in an error

Answer 1

in my root projects build.gradle I defined a task to copy all subprojects jar files into the /build/libs folder of the root project like this:
task build(type: Copy) {
dependsOn subprojects.build
// from subprojects.collect { it.tasks.withType(AbstractArchiveTask) }
from subprojects.collect { it.tasks.withType(Jar) }
into project.rootProject.buildDir.toString() + "/libs"
}
task clean(group:project.rootProject.ext.group, type: Delete, description:"clean jars from subprojects") {
delete fileTree(project.buildDir).include('**/*')
}
you should be able to copy any other build artefacts to the root project in a similar way.

Answer 2

Thanks for your help all. The following, derrived from your input seems to work.
task copyJars(type: Copy) {
dependsOn subprojects.build
from subprojects.collect { it.tasks.withType(Jar) }
into project.rootProject.buildDir.toString() + "/libs"
}
task copyDependencies(type: Copy) {
from subprojects.collect { it.configurations.runtime }
into project.rootProject.buildDir.toString() + "/libs"
}
task copyStartScripts(type: Copy) {
dependsOn copyJars
from subprojects.collect { it.tasks.withType(CreateStartScripts) }
into project.rootProject.buildDir.toString() + "/scripts"
}
task createDistribution() {
apply plugin: 'distribution'
distributions {
main {
contents {
from(copyStartScripts) {
into "bin"
fileMode = 0755
}
from(copyJars) {
into "lib"
}
from(copyDependencies) {
into "lib"
}
}
}
}
}
