在maven中创建可执行jar文件，清单中缺少主类

Question

这是我的pom.xml，我该如何制作一个可执行jar，我在google中读到它需要在manifest.mf中有主类。我尝试使用addind插件，但一无所获           -

您应该使用maven-jar-plugin打包jar文件并提供一个主类：

<build>
    <plugins>
        <!-- ... other plugins ... -->
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-jar-plugin</artifactId>
            <version>3.1.1</version>
            <configuration>
                <archive>
                    <manifest>
                        <!-- Your main class -->
                        <mainClass>sims_for_import.Main</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>
    </plugins>
</build>

您可以在maven central repository上看到最新可用插件版本的列表。
