java - 使用 mvn assembly :single 构建时显示缺少类路径

Question

我正在使用 maven 和 eclipse 构建我的项目。我正在使用运行非常愉快的命令 mvn assembly:single 。但是，当我尝试使用以下方式运行 jar 时:

java Iris-1.0-SNAPSHOT-jar-with-dependencies.jar

我得到:

Exception in thread "main" java.lang.NoClassDefFoundError: target/Iris-1/0-SNAPSHOT-jar-with-dependencies/jar
Caused by: java.lang.ClassNotFoundException: target.Iris-1.0-SNAPSHOT-jar-with-    dependencies.jar
at java.net.URLClassLoader$1.run(URLClassLoader.java:202)
at java.security.AccessController.doPrivileged(Native Method)

at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

此外， list 不包含类路径。生成的 list 看起来像

Build-Jdk: 1.6.0_29
Created-By: Apache Maven
Main-Class: com.maxgarfinkel.iris.commandLine.CommandLineTools

pom 看起来像这样:

1.我怎样才能让类路径显示出来？ 2. 这会让 jar 可以运行吗？

Answer 1

你需要这样做

java -jar Iris-1.0-SNAPSHOT-jar-with-dependencies.jar.

有关更多信息，请参阅此链接 http://docs.oracle.com/javase/tutorial/deployment/jar/run.html

此外， list 也不需要包含类路径(我认为)。
