到目前为止，我已经尝试过以下方法来消除这个错误，但还没有成功
1.DownGraded the JDK from Version 1.7 to jdk1.6.0_18
2.Added the **main class** in the **plugin for org.codehaus.mojo**
<configuration>
<mainClass>C:apache-camel-2.11.0examplescamel-example-smooks-integrationsrcmainjavaexampleMain</mainClass>
</configuration>
我也遇到了类似的问题。
事实证明，我运行
mvn clean package install
正确的方式是
mvn clean install
您的问题是您已经声明了两次exec-maven插件：
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2.1</version>
<executions>
<execution>
<goals>
<goal>java</goal>
</goals>
</execution>
</executions>
<configuration>
<mainClass>C:apache-camel-2.11.0examplescamel-example-smooks-
integrationsrcmainjavaexampleMain< /mainClass>
</configuration>
</plugin>
< plugin>
< groupId>org.codehaus.mojo</groupId>
< artifactId>exec-maven-plugin</artifactId>
< version>1.2</version>
< /plugin>
我也遇到了同样的问题，但在删除了org.codehaus.mojo成功了。
我用这个
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.2</version>
</plugin>
我在使用"org.codehaus.mojo"-"jaxws-maven-plugin"时遇到了类似的问题：无法解决依赖关系。幸运的是，我能够在Eclipse中执行Project>Clean，从而解决了这个问题。
要在IntelliJ中解决此问题
1） 将.fxml文件放入资源目录
2） 在Start方法中，按以下方式定义.fxml文件的路径：Parent root = FXMLLoader.load(getClass().getResource("/sample.fxml"));/似乎为我解决了这个问题：）
