到目前为止，我已经尝试了以下操作来消除此错误，但尚未取得任何成功。
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-2.11.0\examples\camel-example-smooks-integration\src\main\java\example\Main</mainClass>
</configuration>
【问题讨论】：
寻找解决此问题的建议 尝试mvn -X exec:java 启用完整的调试日志记录，您应该有更多信息
我有同样的问题（使用较新的版本），但只是当我尝试从一个带有 PSVM 的新类运行项目时（测试一些方法）。如果我从原始的“主”类运行它，则不会出现此错误。 Main1.class（第一个也是唯一一个使用 PSVM 的类），在 Another.class 上调用方法，但如果我尝试直接运行 Another.class（使用 PSVM），则会引发错误
先生。 Pineda 在这里说得很好，这对我有帮助：***.com/questions/59765574/…
【参考方案1】：
我也遇到过类似的问题。
结果我跑了
mvn clean package install
正确的方法是
mvn clean install
【讨论】：
在 Netbeans 中哪里可以做到这一点？ 我不使用 NetBeans。我在命令行中运行了命令。我记得，Eclipse 允许创建构建任务。 这些命令是等效的。 Maven 将在the lifecycle 中运行所有前面的步骤，因此指定install 意味着package 也将运行，compile 等也将运行。【参考方案2】：
你的问题是你已经声明了两次 exec-maven-plugin ：
<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-2.11.0\examples\camel-example-smooks-
integration\src\main\java\example\Main< /mainClass>
</configuration>
</plugin>
...
< plugin>
< groupId>org.codehaus.mojo</groupId>
< artifactId>exec-maven-plugin</artifactId>
< version>1.2</version>
< /plugin>
【讨论】：
嘿 Pith，我尝试删除我有同样的问题，但删除旧插件后 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>
【讨论】：
【参考方案4】：'org.codehaus.mojo'-'jaxws-maven-plugin' 有类似的问题：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。
【讨论】：
【参考方案5】：在 IntelliJ 中解决这个问题...
1) 将您的 .fxml 文件放入 resources 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:)

以上是关于未能执行目标 org.codehaus.mojo:exec-maven-plugin:1.2:java (default-cli)的主要内容，如果未能解决你的问题，请参考以下文章
Maven 不会运行我的项目：无法执行目标 org.codehaus.mojo:exec-maven-plugin:1.2.1:exec
无法在项目 mavenproject2 上执行目标 org.codehaus.mojo:exec-maven-plugin:1.3.2:exec （默认）：
Maven错误：无法执行目标org.codehaus.mojo：exec-maven-plugin：1.2.1：exec
目标 org.codehaus.mojo:exec-maven-plugin:1.6.0:java 的参数“mainClass”丢失或无效
Maven 和 Java：目标 org.codehaus.mojo:exec-maven-plugin:1.2.1:java 的参数“mainClass”丢失或无效
在 Maven 中从测试范围运行 main：“目标 org.codehaus.mojo:exec-maven-plugin:1.6.0:java 的参数 'mainClass' 丢失或无效”
