No plugin found for prefix 'exec' in the current project and in the plug in groups org.codehaus.mojo
提问by Jim C
I have read several questions with similar issue and the Help 1 page. Unfortunately, I am stuck.
我已经阅读了几个具有类似问题的问题和帮助 1 页面。不幸的是，我被卡住了。
One possible reason could be caused by proxy but there is no such proxy here. Additionally, all maven projects in my PC have been successfully updated when I update it from Eclipse. So I discard this possibility.
一种可能的原因可能是由代理引起的，但这里没有这样的代理。此外，当我从 Eclipse 更新它时，我的 PC 中的所有 maven 项目都已成功更新。所以我放弃了这种可能性。
Other thing I checked was to look for codehaus in my local repository and I find it (C:\Users\myUser.m2\repository\org\codehaus\mojo).
我检查的另一件事是在我的本地存储库中查找 codehaus，我找到了它 (C:\Users\myUser.m2\repository\org\codehaus\mojo)。
Another try, I tried add pluginGroups/pluginGroup in settings. The project is a very simple hello word using spring batch with only a Tasklet and its execute method. There isn't public static void main method.
另一次尝试，我尝试在设置中添加 pluginGroups/pluginGroup。该项目是一个非常简单的 hello word，使用 spring 批处理，只有一个 Tasklet 及其执行方法。没有 public static void main 方法。
Command.exe with the whole error printed after I added the Matteo recommendation:
在添加 Matteo 建议后打印了整个错误的 Command.exe：

采纳答案by A_Di-Matteo
You should configure your pom file to at least declare the Exec Maven Pluginas following:
您应该将 pom 文件配置为至少声明Exec Maven 插件如下：
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1</version>
</plugin>
</plugins>
</build>
As such, you will be able to use the exec:javaplugin:goal command.
因此，您将能够使用exec:javaplugin:goal 命令。
You can even avoid the options:
您甚至可以避免以下选项：
-Dexec.mainClass=org.springframework.batch.core.launch.support.CommandLineJobRunner -Dexec.args="com.test.config.HelloWorldJobConfig helloWorldJob"
By configuring them in your POM as part of the same plugin configuration as following:
通过在 POM 中将它们配置为相同插件配置的一部分，如下所示：
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1</version>
<configuration>
<mainClass>org.springframework.batch.core.launch.support.CommandLineJobRunner</mainClass>
<arguments>
<argument>com.test.config.HelloWorldJobConfig</argument>
<argument>helloWorldJob</argument>
</arguments>
</configuration>
</plugin>
As you can see, we are actually saying to the plugin where to find the main class and its arguments. You could then hence simply invoke:
如您所见，我们实际上是在告诉插件在哪里可以找到主类及其参数。因此，您可以简单地调用：
mvn compile exec:java
And it should perform the same expected results.
它应该执行相同的预期结果。
Update1
Indeed, your maven execution is having troubles to access the plugin metadata on the network:
Update1
确实，您的 Maven 执行在访问网络上的插件元数据时遇到了麻烦：
[WARNING] Failed to retrieve plugin descriptor for org.codehaus.mojo:exec-maven- plugin:1.1: Plugin org.codehaus.mojo:exec-maven-plugin:1.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.codehaus .mojo:exec-maven-plugin:jar:1.1
[警告] 无法检索 org.codehaus.mojo:exec-maven-plugin:1.1 的插件描述符：插件 org.codehaus.mojo:exec-maven-plugin:1.1 或其依赖项之一无法解析：无法读取org.codehaus 的工件描述符 .mojo:exec-maven-plugin:jar:1.1
Update2
If you keep on having issues with the plugin prefix, then indeed it might depend on your network settings. A quick check could be performed by invoking the Exec Maven Plugin not via its plugin prefix (exec) but via full qualified name as following:
Update2
如果您一直遇到插件前缀问题，那么它确实可能取决于您的网络设置。可以通过调用 Exec Maven 插件而不是通过其插件前缀 ( exec) 而是通过完全限定名称来执行快速检查，如下所示：
mvn compile mvn org.codehaus.mojo:exec-maven-plugin:1.1:java
Note the pattern: we are invoking maven, then a groupId:artifactId:version:goal, it will be exactly the same. That will check whether your pom configuration (and plugin configuration) is correct or not.
请注意模式：我们正在调用 maven，然后是 groupId:artifactId:version:goal，它将完全相同。这将检查您的 pom 配置（和插件配置）是否正确。
Update3
As seen in your output log, Maven is trying to access repositories via https(note the final 's'), hence via SSL and then having issues with certificates as part of the build output:
Update3
正如您的输出日志中所见，Maven 正在尝试通过https（注意最后的 's'）访问存储库，因此通过 SSL，然后将证书问题作为构建输出的一部分：
sun .security.validator.ValidatorException: PKIX path building failed: sun.security. provider.certpath.SunCertPathBuilderException: unable to find valid certificatio n path to requested target
sun .security.validator.ValidatorException：PKIX 路径构建失败：sun.security。provider.certpath.SunCertPathBuilderException：无法找到请求目标的有效证书路径
You have two options then:
那么你有两个选择：
- Tell maven to ignore SSL errors, as described in another SO answer
- Check your settings firstly via running
mvn help:effective-settingsto make sure you get the real settings applied by maven (if the command will work actually), then re-configuring non SSL repositories in your settings with the alternative on another SO answer
