java - 将项目作为 .jar 执行时找不到 bluecove jar

Question

当我从 Eclipse 运行我的 Java Swing 应用程序时，它运行良好。但是当我尝试将它作为 jar 文件运行时，它无法识别我引用的库（bluecove-2.1.1-SNAPSHOT.jar）并给我以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: javax/bluetooth/UUID

Caused by: java.lang.ClassNotFoundException: javax.bluetooth.UUID
at java.net.URLClassLoader$1.run(URLClassLoader.java:366)
at java.net.URLClassLoader$1.run(URLClassLoader.java:355)

at java.lang.ClassLoader.loadClass(ClassLoader.java:425)
at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308)
at java.lang.ClassLoader.loadClass(ClassLoader.java:358)

我创建 jar 文件的方式有问题还是 bluecove jar 本身有问题？

Answer 1

这很简单

右键单击项目->构建路径->配置构建路径->订购和导出

如果没有复选标记，请检查是否标记了 bluecove 库

Answer 2

The problem was that I was trying to export it to a jar and then manually adding the main class in manifest.MD and the jars it was using. All I had to do was export it to an 'executable' jar and check the extract all jars option while exporting :)
