“没有主清单属性"使用IntelliJ IDEA创建Kotlin jar时 [英] "No main manifest attribute" when creating Kotlin jar using IntelliJ IDEA

问题描述

从我的Kotlin代码创建一个jar并运行它时，它显示无主清单属性". 当查看manifest.mf时，它具有以下内容:

When creating a jar from my Kotlin code and running it, it says "No main manifest attribute". When looking at the manifest.mf, it has this content:

Manifest-Version: 1.0

在源文件中查看文件时，它具有以下内容:

When looking at the file in the source, it has this content:

Manifest-Version: 1.0
Main-Class: MyMainClass

当手动将源清单复制到jar时，它可以完美运行.

When manually copying the source manifest to the jar, it runs perfectly.

推荐答案

如果任何相关的jar都具有MANIFEST.MF文件，它将覆盖定义Main-Class的自定义文件.

If any of the dependent jars has a MANIFEST.MF file, it will override your custom one which defines the Main-Class.

为了解决此问题，您应该执行以下操作:

In order to address this problem you should do the following:

• 禁用按字母顺序排序
• 更改项目顺序，使具有META-INF/MANIFEST.MF文件的项目成为列表
• 您的自定义MANIFEST.MF将由IntelliJ IDEA提取，并显示在罐子中 人工产物.

• Disable the alphabetical ordering
• Change items ordering so that item which has META-INF/MANIFEST.MF file is the first in the list
• Your custom MANIFEST.MF will be picked up by IntelliJ IDEA and displayed for the jar artifact.

您也可以改用Gradle或Maven来生成胖子.

You can also use Gradle or Maven to generate the fat jar instead.
