发布失败的提示信息是说找不到tool.jar？看不懂是哪里出了问题。
maven-publish.gradle完全是照着视频抄的，应该也没抄错：

apply plugin: "maven" // 使用maven插件中的发布功能

// 公共参数
Properties gradleProperties = new Properties()
gradleProperties.load(project.rootProject.file("gradle.properties").newDataInputStream())
def VERSION_NAME = gradleProperties.getProperty("VERSION_NAME")
def POM_URL = gradleProperties.getProperty("POM_URL")
def GROUP_ID = gradleProperties.getProperty("GROUP_ID")

// 子工程
Properties projectGradleProperties = new Properties()
projectGradleProperties.load(project.file("gradle.properties").newDataInputStream())
def POM_ARTIFACT_ID = projectGradleProperties.getProperty("POM_ARTIFACT_ID")

println("maven-publish VERSION_NAME = " + VERSION_NAME)
println("maven-publish POM_URL = " + POM_URL)
println("maven-publish GROUP_ID = " + GROUP_ID)
println("maven-publish POM_ARTIFACT_ID = " + POM_ARTIFACT_ID)

uploadArchives {
    repositories {
        mavenDeployer {
            // 填入发布信息
            repository(url: uri(POM_URL)) {
                pom.groupId = GROUP_ID
                pom.version = VERSION_NAME
                pom.artifactId = POM_ARTIFACT_ID
            }

            pom.whenConfigured { pom ->
                pom.dependencies.forEach { dep ->
                    if (dep.getVersion() == "unspecified") {
                        dep.setGroupId(GROUP_ID)
                        dep.setVersion(VERSION_NAME)
                    }
                }
            }
        }
    }
}

请老师帮忙看看是哪里写错了？
