【问题讨论】：

那些是 maven jars，他们是怎么进来的？你能发布你的mvn help:effective-pom 吗？
@JigarJoshi 已更新。是的，它们是 Maven 罐子，但我认为它们不会影响战争文件。对吗？
可以附上mvn dependency:tree命令的结果吗？

标签： java maven war maven-plugin

【解决方案1】：

您应该更新要在 war 文件中排除的依赖项的范围部分。

<scope>provided</scope>

提供的范围表示依赖将在编译期间存在，但不会包含在war文件中。

对于 maven 相关的 jar，您可以使用下面的方法排除它们。

<configuration>
      <packagingExcludes>WEB-INF/lib/*.jar</packagingExcludes>
</configuration>

【解决方案2】：

尝试改变

<dependency>
  <groupId>org.mybatis.generator</groupId>
  <artifactId>mybatis-generator-maven-plugin</artifactId>
  <version>1.3.2</version>
  <scope>compile</scope>
  <exclusions>
    <exclusion>
      <artifactId>google-collect</artifactId>
      <groupId>com.google.code.google-collections</groupId>
    </exclusion>
  </exclusions>
</dependency>

到

<dependency>
  <groupId>org.mybatis.generator</groupId>
  <artifactId>mybatis-generator-maven-plugin</artifactId>
  <version>1.3.2</version>
  <scope>provided</scope>
  <exclusions>
    <exclusion>
      <artifactId>google-collect</artifactId>
      <groupId>com.google.code.google-collections</groupId>
    </exclusion>
  </exclusions>
</dependency>

编辑：以上只是快速修复，一般你应该摆脱这种类型的依赖，插件的使用应该在pluginManagement中定义。

【讨论】：

永远不要将插件用作依赖项，这是完全错误的。
@khmarbaise 你是完全正确的。我只是给出了最简单的应该用作快速修复。将编辑我的帖子。

【解决方案3】：

简单回答。永远不要使用 maven 插件作为依赖项，因为它们不属于依赖项。这就是为什么在你的构建中出现这些奇怪的工件的原因。
