在当前项目和插件组 org.codehaus.mojo 中找不到前缀 'exec' 的插件
No plugin found for prefix 'exec' in the current project and in the plug in groups org.codehaus.mojo
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，我被困住了。
一个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。
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)。
再试一次，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 在我添加 Matteo 推荐后打印出整个错误：

您应该配置您的 pom 文件以至少声明 Exec Maven Plugin 如下：
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1</version>
</plugin>
</plugins>
</build>
因此，您将能够使用 exec:java plugin:goal 命令。
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"
通过在您的 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>
如您所见，我们实际上是在告诉插件在哪里可以找到主要 class 及其参数。然后你可以简单地调用：
mvn compile exec:java
它应该执行相同的预期结果。
更新1
实际上，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
更新2
如果您继续遇到插件前缀问题，那么它确实可能取决于您的网络设置。可以通过调用 Exec Maven 插件来执行快速检查，而不是通过其插件前缀 (exec)，而是通过如下的完整限定名称：
mvn compile mvn org.codehaus.mojo:exec-maven-plugin:1.1:java
注意模式：我们调用 Maven，然后调用 groupId:artifactId:version:goal，它会完全一样。这将检查您的 pom 配置（和插件配置）是否正确。
更新3
正如您在输出日志中看到的那样，Maven 正在尝试通过 https（注意最后的 's'）访问存储库，因此通过 SSL，然后在构建输出中遇到证书问题：
sun
.security.validator.ValidatorException: PKIX path building failed: sun.security.
provider.certpath.SunCertPathBuilderException: unable to find valid certificatio
n path to requested target
那么你有两个选择：
- 告诉 maven 忽略 SSL 错误，如另一个 SO answer
中所述
- 首先通过 运行
mvn help:effective-settings 检查您的设置以确保您获得 maven 应用的真实设置（如果该命令实际有效），然后 re-configuring 非 SSL 存储库您的设置与另一个 SO answer 上的替代项

一个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。

您应该配置您的 pom 文件以至少声明 Exec Maven Plugin 如下：
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>exec-maven-plugin</artifactId>
<version>1.1</version>
</plugin>
</plugins>
</build>
因此，您将能够使用 exec:java plugin:goal 命令。
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"
通过在您的 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>
如您所见，我们实际上是在告诉插件在哪里可以找到主要 class 及其参数。然后你可以简单地调用：
mvn compile exec:java
它应该执行相同的预期结果。
更新1
实际上，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
更新2
如果您继续遇到插件前缀问题，那么它确实可能取决于您的网络设置。可以通过调用 Exec Maven 插件来执行快速检查，而不是通过其插件前缀 (exec)，而是通过如下的完整限定名称：
mvn compile mvn org.codehaus.mojo:exec-maven-plugin:1.1:java
注意模式：我们调用 Maven，然后调用 groupId:artifactId:version:goal，它会完全一样。这将检查您的 pom 配置（和插件配置）是否正确。
更新3
正如您在输出日志中看到的那样，Maven 正在尝试通过 https（注意最后的 's'）访问存储库，因此通过 SSL，然后在构建输出中遇到证书问题：
sun .security.validator.ValidatorException: PKIX path building failed: sun.security. provider.certpath.SunCertPathBuilderException: unable to find valid certificatio n path to requested target
那么你有两个选择：
- 告诉 maven 忽略 SSL 错误，如另一个 SO answer 中所述
- 首先通过 运行
mvn help:effective-settings检查您的设置以确保您获得 maven 应用的真实设置（如果该命令实际有效），然后 re-configuring 非 SSL 存储库您的设置与另一个 SO answer 上的替代项
