[英]Netbeans Maven Project Not adding Main Class to Manifest
I am having a similar problem to this question. 我对这个问题有类似的问题。 I have tried all the suggestions listed and am still at a loss.
我已经尝试了列出的所有建议,但仍然不知所措。 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.
我的问题是我正在尝试构建一个maven项目并将其分发给其他机器,但jar文件没有填充正确的Manifest。 Each time I build and run I get the following error:
no main manifest attribute, in myjar.jar
. 每次构建和运行时,我都会收到以下错误:
no main manifest attribute, in myjar.jar
。 Is there some sort of configuration file I need to edit? 我需要编辑某种配置文件吗? I just don't know what is going on.
我只是不知道发生了什么。 I have attempted this fix also, but to no avail.
我也试过这个修复 ,但无济于事。
You can add it into project's pom file, inside <project>
tag: 您可以将其添加到项目的pom文件中,在
<project>
标记内:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<manifest>
<mainClass>your.main.class</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
Another option is to use the maven shade plugin
. 另一种选择是使用
maven shade plugin
。 Unlike the maven jar plugin
showed by tigran, the maven shade plugin
includes your dependencies in the generated jar. 与tigran显示的
maven jar plugin
不同, maven shade plugin
包含生成的jar中的依赖项。 A sample usage of the plugin is : 该插件的示例用法是:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.0</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<transformers>
<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
<mainClass>your.main.Class</mainClass>
</transformer>
</transformers>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
