使用阿里云的url创建的spring boot项目，无法打包

Question

使用阿里云的url创建的spring boot项目，运行一切正常，打包时出现警告：

[WARNING] Plugin validation issues were detected in 2 plugin(s)
[WARNING] 
[WARNING]  * org.apache.maven.plugins:maven-compiler-plugin:3.8.1
[WARNING]  * org.apache.maven.plugins:maven-resources-plugin:3.3.0
[WARNING] 
[WARNING] For more or less details, use 'maven.plugin.validation' property with one of the values (case insensitive): [BRIEF, DEFAULT, VERBOSE]
[WARNING] 

项目原有的pom依赖我没有动过，只是新增了其他依赖：

起初我以为是两个版本不对应，于是将maven-resources-plugin的版本也改成了3.8.1，但是这样直接就报错了：

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-resources-plugin</artifactId>
            <version>3.8.1</version> <!-- 或者更新到最新版本 -->
        </plugin>

Cannot resolve plugin org.apache.maven.plugins:maven-resources-plugin:3.8.1

以下回复参考：皆我百晓生、券券喵儿等免费微信小程序作答:

这个问题可能是由于Maven仓库中的插件版本不兼容导致的。你可以尝试以下方法解决这个问题：

1. 将maven-compiler-plugin和maven-resources-plugin的版本统一为最新版本，例如：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.1</version>
</plugin>
<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-resources-plugin</artifactId>
    <version>3.8.1</version>
</plugin>

1. 如果上述方法仍然无法解决问题，你可以尝试删除本地Maven仓库中的相关插件文件夹，然后重新构建项目。本地Maven仓库的默认位置通常在用户目录下的.m2/repository文件夹中。删除对应的插件文件夹后，Maven会在构建过程中自动下载最新的插件版本。

2. 如果问题仍然存在，你可以尝试使用阿里云的Maven镜像仓库来加速依赖下载。在项目的pom.xml文件中添加以下内容：

<repositories>
    <repository>
        <id>aliyunmaven</id>
        <url>https://maven.aliyun.com/repository/public</url>
        <releases>
            <enabled>true</enabled>
        </releases>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

这将使Maven从阿里云的镜像仓库下载依赖，可能会解决插件版本不兼容的问题。
