android studio 生成maven 多个module依赖问题

我有一个工程 叫xxx_Libray，里边有2个module 分别为lib1、bli2 。lib2依赖lib1。编译lib2的gradle生成的pom文件格式如下：

     <dependency>
      <groupId>xxx_Libray</groupId>//这里groupId 和 version 有问题
      <artifactId>lib1</artifactId>
      <version>unspecified</version>
      <scope>compile</scope>
    </dependency>

    <dependency>
      <groupId>com.android.support</groupId>
      <artifactId>design</artifactId>
      <version>23.1.1</version>
      <scope>compile</scope>
    </dependency>

    <dependency>
      <groupId>com.android.support</groupId>
      <artifactId>recyclerview-v7</artifactId>
      <version>23.+</version>
      <scope>compile</scope>
    </dependency>

在使用依赖的项目里

 dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'xxx.xxx.xxx:1.0'
}

提示Error:Failed to resolve: XXX_Libray:lib1:unspecified

 maven_push.gradle

 apply plugin: 'maven'
apply plugin: 'signing'

configurations {
    deployerJars
}

repositories {
    mavenCentral()
}

// 判断版本是Release or Snapshots
def isReleaseBuild() {
    return !VERSION.contains("SNAPSHOT");
}

// 获取仓库url
def getRepositoryUrl() {
    return isReleaseBuild() ? RELEASE_URL : SNAPSHOT_URL;
}

uploadArchives {
    repositories {
        mavenDeployer {
            beforeDeployment {
                MavenDeployment deployment -> signing.signPom(deployment)
            }

            pom.version = VERSION
            pom.artifactId = POM_ARTIFACT_ID
            pom.groupId = GROUP

            repository(url: getRepositoryUrl()) {
                authentication(userName: NAME, password: PASSWORD) // maven授权信息
            }


        }
    }
}

// 进行数字签名
signing {
    // 当 发布版本 & 存在"uploadArchives"任务时，才执行
    required { isReleaseBuild() && gradle.taskGraph.hasTask("uploadArchives") }
    sign configurations.archives
}

我觉得是pom生成依赖的问题，可是不知道怎么改，求帮忙。万分感激
