gradle uploadArchives for multiple subproject with different maven group and version - gradle

Question

I have the following build.gradle and it works for the individual sub project (or all of them if I copy paste it):
def group = 'com.my.pgk'
def artifact = project.name
def version = '1.0.0'
sourceCompatibility = JavaVersion.VERSION_1_7
targetCompatibility = JavaVersion.VERSION_1_7
uploadArchives {
repositories {
mavenDeployer {
def finalPath = 'file://' + LocalMavenRepoPath.toString()
println group
println finalPath
repository url: finalPath
pom.groupId = group
pom.artifactId = artifact
pom.version = version
pom.packaging = 'jar'
}
}
}
jar {
archiveName = artifact + "-" + version + ".jar"
}
task sourcesJar(type: Jar, dependsOn: classes) {
classifier = 'sources'
archiveName = artifact + "-v" + version + "-src.jar"
from sourceSets.main.allSource
}
task javadocJar(type: Jar, dependsOn: javadoc) {
classifier = 'javadoc'
archiveName = artifact + "-v" + version + "-doc.jar"
from javadoc.destinationDir
}
artifacts {
archives sourcesJar
archives javadocJar
}
It is doing exactly what I want it to...
Trying to move this to the root project build.gradle doesn't because the variables defined in the subprojects are not updated when uploadArchives is called.
How can I work around this?

Answer 1

You need the subprojects to be configured first so that gradle is aware of the subproject variables before the root build.gradle is configured. You can force a bottom-up configuration by using:
evaluationDependsOnChildren()

Answer 2

In a project with a single root and two subprojects, you can create a common gradle script in the root project and apply it to each of the subprojects.
Root Project:
build.gradle
//nothing to see here
Root Project: common.gradle
if (!project.hasProperty("commonVar")) {
ext.commonVar = "unset"
}
task printCommonVar() {
println commonVar
}
Root Project: settings.gradle
rootProject.name = 'GradleGroupProject'
// Find the directories containing a "build.gradle" file in the root directory
// of the project. That is, every directory containing a "build.gradle" will
// be automatically the subproject of this project.
def subDirs = rootDir.listFiles(new FileFilter() {
public boolean accept(File file) {
if (!file.isDirectory()) {
return false
}
if (file.name == 'buildSrc') {
return false
}
return new File(file, 'build.gradle').isFile()
}
});
subDirs.each { File dir ->
include dir.name
}
Subproject 1: build.gradle
ext.commonVar = "subproject1"
apply from: rootProject.file('common.gradle')
Subproject 2: build.gradle
ext.commonVar = "subproject2"
apply from: rootProject.file('common.gradle')
The ordering between ext.commonVar = "subproject2" and apply from: rootProject.file('common.gradle') is important.
