Netbeans Maven Project Not adding Main Class to Manifest
提问by derigible
I am having a similar problem to thisquestion. I have tried all the suggestions listed and am still at a loss. My issue is that I am trying to build a maven project and distribute it to other machines, but the jar files are not being populated with a correct Manifest. Each time I build and run I get the following error: no main manifest attribute, in myjar.jar. Is there some sort of configuration file I need to edit? I just don't know what is going on. I have attempted this fixalso, but to no avail.
我遇到了与此问题类似的问题。我已经尝试了列出的所有建议，但仍然不知所措。我的问题是我正在尝试构建一个 Maven 项目并将其分发到其他机器，但是 jar 文件没有填充正确的 Manifest。每次构建和运行时，我都会收到以下错误：no main manifest attribute, in myjar.jar. 我需要编辑某种配置文件吗？我只是不知道发生了什么。我也尝试过此修复程序，但无济于事。

<configuration>
<archive>
<manifest>
<mainClass>your.main.class</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>

Another option is to use the maven shade plugin. Unlike the maven jar pluginshowed by tigran, the maven shade pluginincludes your dependencies in the generated jar.
A sample usage of the plugin is :
另一种选择是使用maven shade plugin. 与maven jar plugintigran 显示的不同，它maven shade plugin在生成的 jar 中包含您的依赖项。该插件的示例用法是：

<artifactId>maven-shade-plugin</artifactId>
<version>2.0</version>
<executions>
<execution>

<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>your.main.Class</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
