在包含记录类型的 Java 16 代码上使用 maven-plugin-plugin 版本 3.6.0 时出错

Question

我正在创建一个 Maven 插件使用

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-plugin-plugin</artifactId>
</plugin>

我想将我的插件所需的 JDK 版本及其依赖项升级到 16，但似乎有问题：

在org.apache.maven.plugin-tools:maven-plugin-tools-annotations:3.6.0中，可以看到以下构造函数（在DefaultMojoAnnotationsScanner.analyzeClassStream()中调用堆栈跟踪）

    public MojoClassVisitor( Logger logger )
    {
        super( Opcodes.ASM7 );
        this.logger = logger;
    }

当 ASM 需要版本 8 来处理记录类型时，它将 ASM API 版本硬连接到 ASM7。 在这些 Maven 插件的新版本发布之前，有什么方法可以升级上述 class 的 ASM 依赖项，而无需分叉和修补所有可能的 Z9115C10980645C41313F244AC1A377F 插件？ 在插件上使用通常的<excludes>和<dependency>标记在这里不起作用，因为即使我升级依赖项本身， MojoClassVisitor仍然会将 API 版本硬编码为 ASM7。

我还创建了https://issues.apache.org/jira/browse/MPLUGIN-371来跟踪这个

这似乎是已为下一版本 3.6.1 修复的公认问题： https://issues.apache.org/jira/browse/MPLUGIN-369

一种解决方法是添加：

<repositories>
    <repository>
        <id>apache-snapshot-repository</id>
        <name>Apache Snapshot Repository</name>
        <url>https://repository.apache.org/snapshots/</url>
    </repository>
</repositories>

然后将此依赖项添加到maven-plugin-plugin ：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-plugin-plugin</artifactId>
    <dependencies>
        <dependency>
            <groupId>org.apache.maven.plugin-tools</groupId>
            <artifactId>maven-plugin-tools-annotations</artifactId>
            <version>3.6.1-SNAPSHOT</version>
        </dependency>
    </dependencies>
</plugin>
