JAR:无法找到或加载主类

没有编写用于连接到Hive的Java类,并做了gradle任务来构建具有所有依赖项的JAR

task Hive(type: Jar) {
    manifest {
        attributes 'Implementation-Title': 'Gradle Jar File Example',
                'Implementation-Version': version,
                'Main-Class': 'ru.prometheus.nodeexporters.Hive'
    }
    baseName = project.name + '-Node_Exporter'
//    from('src/main/java') {
//        include 'resources/*'
//    }
    from {
        configurations.runtime.collect {
            it.isDirectory() ? it : zipTree(it)
        }
    }
    with jar
}

执行任务

12:55:46: Executing task 'Hive'...

之后检查了JAR

确实存在主类,但是否尝试执行返回的错误

c:\Servers\Repository\PrometheusNodeExporters\Hive\build\libs>java -jar Hive-Nod
e_Exporter-1.0-SNAPSHOT.jar
Error: Could not find or load main class ru.prometheus.nodeexporters.Hive

如何解决这个“简单”的问题?
