gradlew 发布错误，无法在我的存储库上创建副本

如何解决gradlew 发布错误，无法在我的存储库上创建副本

我是 Nexus 的新手，试图运行 gradlew publish ，但给出如下所述的错误：

    C:\>gradlew publish
> Task :publishMavenPublicationToNexusRepository Failed

FAILURE: Build Failed with an exception.

* What went wrong:
Execution Failed for task ':publishMavenPublicationToNexusRepository'.
> Failed to publish publication 'maven' to repository 'nexus'
   > Invalid publication 'maven': artifact file does not exist: 

我正在尝试参加一些 Bootcamp 培训，这是我得到的代码：

---

plugins {
    id 'java'
    id 'org.springframework.boot' version '2.2.2.RELEASE'
    id 'io.spring.dependency-management' version '1.0.8.RELEASE'

    repositories {
        maven {
            name 'nexus'
            url "http://139.59.150.201:8081/repository/maven-snapshots/"
            credentials {
                username project.repoUser
                password project.repoPassword
            }
        }

    }
}
