通过gradle将本地jar发布到nexus存储库

Question

我的本​​地系统中有一些jar文件，我想使用Gradle脚本发布，但到目前为止我找不到任何解决方案。 我能够发布我的构建生成的工件，但我想发布我本地系统中的jar。 我试图将这个工件声明为跟随但是它抛出了错误：

publishing {
  publications {
    mavenJava(MavenPublication) {
        artifact projJar

    //This is jar file other than my built file which I want to upload (there are same files more in number to be uploaded):
        artifact 'D:/myworkspace/Test/LocalJar.jar'
        artifact source: projJar, classifier: 'src', extension: 'jar'

    }
}
repositories {
    maven {
        credentials {
            username 'user'
            password 'password'
          }
        url "http://IP:Port/repository/RepoName/"
    }
}

}

错误消息是：

 *What went wrong:
  Execution failed for task:publishMavenJavaPublicationToMaven2Repository'.
  > Failed to publish publication 'mavenJava' to repository 'maven2'
  > Invalid publication 'mavenJava': multiple artifacts with the identical extension and classifier ('jar', 'null').

请指导我如何将我的本地jar文件发布到nexus存储库（我当地有很多文件要发布）
