Java MAVEN，Netbeans平台：找不到主类

java maven netbeans

Java MAVEN，Netbeans平台：找不到主类,java,maven,netbeans,netbeans-platform,Java,Maven,Netbeans,Netbeans Platform,我遵循这个教程：我有一个问题我试图创建示例“maven crud示例应用程序”和我的“maven netbeans应用程序”，但总是出现相同的错误。当我运行项目时，会出现以下异常： --- nbm-maven-plugin:3.3:run-platform (default-cli) @ application --- Executing: /bin/sh -c "/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/a

我遵循这个教程：我有一个问题

我试图创建示例“maven crud示例应用程序”和我的“maven netbeans应用程序”，但总是出现相同的错误。当我运行项目时，会出现以下异常：

--- nbm-maven-plugin:3.3:run-platform (default-cli) @ application ---
Executing: /bin/sh -c "/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/foo/bin/foo" --userdir '"/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/userdir"' -J-Dnetbeans.logger.console=true -J-ea --branding foo --jdkhome /usr/local/java/jdk1.6.0_45
Exception in thread "main" java.lang.NoClassDefFoundError: maven//MavenCRUDSample/application/target/userdir/var/log/heapdump/hprof
Caused by: java.lang.ClassNotFoundException: maven.MavenCRUDSample.application.target.userdir.var.log.heapdump.hprof

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

找不到主类：maven/MavenCRUDSample/application/target/userdir/var/log/heapdump.hprof。程序将退出。

在本教程中，我没有看到在主类中进行任何修改

我在没有MAVEN的情况下也做了同样的教程，效果很好：

有了这个错误，我无法运行我的应用程序并打开我的netbeans平台窗口。有人知道我为什么有这个吗

我使用的是带有jdk1.6.0_45和maven-3.2.1的Netbeans 6.9.1 操作系统：Ubuntu 64位

编辑：我有4个pom.xml：

父级：crud示例应用程序–netbeans平台应用程序

crud示例应用程序–基于Netbeans平台的应用程序

crud示例应用程序-平台应用程序品牌资源

crud示例应用程序–示例Netbeans模块

很抱歉，我无法拆分它

通过main（）运行项目：

avec les参数：

exec.classpathScope=${classPathScope}
exec.args=-classpath %classpath ${packageClassName}
exec.executable=java "

谢谢，

问题解决，当netbeans执行时：

 /bin/sh -c "/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/foo/bin/foo" --userdir '"/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/userdir"' -J-Dnetbeans.logger.console=true -J-ea --branding foo --jdkhome /usr/local/java/jdk1.6.0_45

它不喜欢maven和test之间的空间。我重命名了我的文件夹，它就可以工作了

你能在这个问题中添加你的代码吗？没有代码我们怎么能给出答案？代码是由Netbeans自动生成的，我没有做任何更改。我认为代码不是问题所在。如果我启动了一个netbeans平台项目，没有任何代码（在我的教程中创建netbeans平台应用程序的部分）；我也有同样的问题。请向我们展示您的pom.xml和您如何执行mvnChange to eclipse的命令行-它将消除您在使用NetBeans时遇到的50%的问题：）

exec.classpathScope=${classPathScope}
exec.args=-classpath %classpath ${packageClassName}
exec.executable=java "

 /bin/sh -c "/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/foo/bin/foo" --userdir '"/home/pea-rep/NetBeansProjects/JDK6/test maven//MavenCRUDSample/application/target/userdir"' -J-Dnetbeans.logger.console=true -J-ea --branding foo --jdkhome /usr/local/java/jdk1.6.0_45
