Question

尝试使用Cmd打包，并获得[警告] JAR将为空-没有内容标记为包含！

构建成功，但根据警告生成的jar文件为空

对不起，还尝试了其他解决方案，最后落入此处，我对java和maven还是陌生的。请帮助

在尝试 mvn全新安装-DskipTests 时，它发出警告，因为jar为空

当我使用以下内容更新pom.xml（maven-jar-plugin）

                <plugin>
                    <artifactId>maven-jar-plugin</artifactId>
                    <version>3.0.2</version>
                    <configuration>
                        <classesDirectory>src</classesDirectory>
                        <excludes>
                            <exclude>**</exclude>
                        </excludes>
                    </configuration>
                </plugin>

瓶子生产没有错误，但大小为3KB-是吗？

但是当我尝试执行jar时

java -jar rlso_smoke-0.0.1-SNAPSHOT.jar

收到以下错误：

no main manifest attribute, in rlso_smoke-0.0.1-SNAPSHOT.jar

我看到了其他需要Main class的答案。但是我也看到了testng不需要Main Class。

Answer 1

                    <excludes>
                        <exclude>**</exclude>
                    </excludes>

这是对maven-jar-plugin的指示，用于从jar中排除所有文件。因此产生了空罐子。删除此部分，然后重试。

警告JAR将为空-未标记任何内容
