MAVEN，Netbeans平台：无法找到主类

时间：2014-05-21 08:44:21

标签： java maven netbeans netbeans-platform

我遵循本教程：https://platform.netbeans.org/tutorials/nbm-maven-crud.html我遇到了问题。

我尝试创建示例“maven crud示例应用程序”和我的“maven netbeans应用程序”，我总是得到同样的错误。当我运行项目时，我得到以下异常：

--- 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 java.net.URLClassLoader$1.run(URLClassLoader.java:202)
        at java.security.AccessController.doPrivileged(Native Method)
        at java.net.URLClassLoader.findClass(URLClassLoader.java:190)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:306)
        at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301)
        at java.lang.ClassLoader.loadClass(ClassLoader.java:247)

无法找到主类：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

进行任何修改

我在没有MAVEN的情况下做了相同的教程，它可以工作：https://platform.netbeans.org/tutorials/nbm-crud.html

出现此错误，我无法运行我的应用程序并拥有netbeans平台窗口。有人知道我为什么这么做？

我在Netbeans 6.9.1 with jdk1.6.0_45 and maven-3.2.1 OS : Ubuntu 64bit

编辑： 我有4个pom.xml：

父级：crud-sample-application - netbeans平台应用程序

crud-sample-application - 基于Netbeans平台的应用程序

crud-sample-application - 平台应用程序品牌资源

crud-sample-application - 示例Netbeans模块

抱歉，我无法拆分它。

我使用netbeans运行我的应用程序==＆gt;运行项目：

install nbm:run-platform

通过main（）运行项目：

process-classes org.codehaus.mojo:exec-maven-plugin:1.1.1:exec

avec les arguments：

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

谢谢， 微米。

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。我重命名我的文件夹，它的工作原理。
