我知道这个问题已经被问了一百万遍了,但是我似乎找不到解决它的方法。

问题是,当我使用以下命令运行JAR文件java -jar MYFATJAR.jar时:

openjdk version "1.8.0_191-1-ojdkbuild"
OpenJDK Runtime Environment (build 1.8.0_191-1-ojdkbuild-b12)
OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode)

我收到以下错误:

Error: Could not find or load main class PACKAGE_PATH.MAINCLASSNAME

但是当我使用以下命令运行相同的命令时

java version "1.8.0_212"
Java(TM) SE Runtime Environment (build 1.8.0_212-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.212-b10, mixed mode)

罐子运行良好。

我使用Gradle编译JAR。这是缩短的build.grade文件:

// build.gradle

plugins {
    id 'java'
    id 'application'
}

jar {
    manifest {
        attributes (
                "Main-Class": "org.me.logreader.App",
                "Specification-Title": "Log Reader",
                "Specification-Vendor" : "ME",
                "Implementation-Title"   : "Log Reader",
                "Implementation-Vendor" : "ME"
        )
    }

    archiveName = "LogReader.jar"
    from {
        configurations.compile.collect {it.isDirectory() ? it : zipTree(it)}
    }
}

...

如果我用WinRAR打开JAR,则看到它显示为: enter image description here

项目结构如下:

src
   -main
        -java
           -org.me.logreader
               -controllers
               -model
               -parsers
               -version
               -views
               -workers
               App.java

更新 MANIFEST.MF文件的内容:

Manifest-Version: 1.0
Implementation-Title: Log Reader
Specification-Vendor: ME
Specification-Title: Log Reader
Main-Class: org.kobbigal.logreader.App
Implementation-Vendor: ME
