Question

我使用maven-assembly-plugin创建一个jar-with-dependencies。当我执行.jar文件时，它会抛出

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/log4j/Logger
    at com.dg.fs.test.integration.main.FSIntegrationTestMain.<clinit>(FSIntegrationTestMain.java:26)
Caused by: java.lang.ClassNotFoundException: org.apache.log4j.Logger
    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)
    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)
    ... 1 more

这是一个子模块，但我不知道为什么这很重要。

我过去曾使用此插件构建了大量与jar依赖的jar。现在它缺少传递依赖。问题是什么？

感谢。

这是pom.xml。

你钉了它，SiKing。在父pom.xml中，它是<scope>provided</scope>。我在项目pom.xml中将其更改为<scope>compile</scope>，它运行正常。

Maven jar-with-dependencies不包含Log4j
