java - Maven 不支持 Maven 依赖插件

Question

我试图从一本书中下载 Spring/Java 代码来运行他们的代码并进行测试，但不幸的是我遇到了错误，

我看到这是一个常见错误，但没有看到我的 pom 文件的修复程序，

pom.xml

Pom文件错误:

maven-dependency-plugin (goals "copy-dependencies", "unpack") is not supported by m2e.
maven-resources-plugin prior to 2.4 is not supported by m2e. Use maven-resources-plugin version 2.4 or later.

Answer 1

@Pace 所说的完全正确，我相信 OP 应该尝试理解 m2e 在做什么。 我个人讨厌 0.10 之后 m2e 的行为，为此他们引入了连接器概念。这个概念很好，但是告诉 Eclipse 如何对不受支持的插件使用react的方法是严重污染 POM，这在我看来很糟糕。切换回旧的 M2E 版本可能会让您的生活更轻松，尽管您会失去一些功能。

从您引用的错误消息回到您的问题:

maven-resources-plugin prior to 2.4 is not supported by m2e. Use maven-resources-plugin version 2.4 or later.

在我看来，m2e 确实支持 maven-resources-plugin >= 2.4(我不确定，我以前没有遇到过与您类似的问题)。尝试在您的 POM 中使用较新版本(2.4 或更高版本，最新版本为 2.6)的 maven-resources-plugin，M2E 可能会为您获取设置。

即

<project>
...
  <build>
    <pluginManagement>
      <plugins>
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-resources-plugin</artifactId>
          <version>2.6</version>
        </plugin>
      </plugins>
       ....
    </pluginManagement>
      ....
  </build>
</project>

标记您使用的插件版本始终是一个好习惯。这导致更“可重现”的构建。
