Netbeans平台:找不到主类

Question

我遵循这个教程:https://platform.netbeans.org/tutorials/nbm-maven-crud.html，我有一个问题。

我尝试创建示例"maven crud示例应用程序"和我的"maven netbeans应用程序"，我总是得到相同的错误。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。

在本教程中，我没有看到对主类

进行任何修改。

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

有了这个错误，我不能运行我的应用程序，并有我的netbeans平台窗口。有人知道我为什么有这个吗?

I'm on 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:crude -sample- Application - netbeans Platform Application

crude -sample-application - Netbeans

crude -sample-application - Platform application branding resources

对不起，我没能把它分开。

我使用netbeans来运行我的应用程序==>运行项目:

install nbm:run-platform

run project via main():

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

avec - les参数

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

谢谢,m .

Answer 1

问题解决，当netbeans执行:

 /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之间的空格。我重命名我的文件夹，它工作。
