how to tell gradle to build and upload archives of dependent projects to local maven

问题

I have a multi-project problem that Gradle's documentation doesn't have any info on (and can't find on stackoverflow also). Any help/guidance will be greatly appreciated.

Here are my project layouts:

project LeftArm: produces a jar file
project RightArm: produces a jar file
project AllArms: depends on projects LeftArm and RightArm and produces a war file

When I run 'gradle build uploadArchives' in AllArms project, it builds LeftArm and RightArm projects but it doesn't upload the jar files (produced by LeftArm and RightArm projects) to local Maven repo.

Here are my build.gradle files:

project LeftArm:
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'maven'

ext.artifactId = 'LeftArm'
archivesBaseName = ext.artifactId // sets filename of warfile/jarfile output
group = 'mygroup'
version = '1.0'

buildscript 
{
    repositories 
    {
    mavenLocal()
    }
}

jar 
{
    from(sourceSets['main'].allJava)
}

dependencies 
{
    compile group: 'javax.validation', name:'validation-api', version:'1.0.0.GA'
    compile group: 'javax.validation', name:'validation-api-sources', version:'1.0.0.GA'
}

def localRepoURL = 'file://' + new File(System.getProperty('user.home'), '.m2/repository').absolutePath

// NOTE: this project will publish to the local Maven repo.
uploadArchives 
{
    repositories 
    {
    mavenDeployer 
    {
        repository(url: localRepoURL)
        addFilter('jar') 
        { 
            artifact, file -> artifact.ext == 'jar'
        }
    }
    }
}

...

project RightArm:
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'maven'

ext.artifactId = 'RightArm'
archivesBaseName = ext.artifactId // sets filename of warfile/jarfile output
group = 'mygroup'
version = '1.0'

buildscript 
{
    repositories 
    {
    mavenLocal()
    }
}

jar 
{
    from(sourceSets['main'].allJava)
}

dependencies 
{
    compile group: 'javax.validation', name:'validation-api', version:'1.0.0.GA'
    compile group: 'javax.validation', name:'validation-api-sources', version:'1.0.0.GA'
}

def localRepoURL = 'file://' + new File(System.getProperty('user.home'), '.m2/repository').absolutePath

// NOTE: this project will publish to the local Maven repo.
uploadArchives 
{
    repositories 
    {
    mavenDeployer 
    {
        repository(url: localRepoURL)
        addFilter('jar') 
        { 
            artifact, file -> artifact.ext == 'jar'
        }
    }
    }
}

uploadArchives isn't meant to be used to install to the local Maven repository. Instead, use the install task.
