provided在测试执行期间，我在我的类路径中看到一个具有范围的 jar 。鉴于provided范围的定义，我不希望该 jar 在任何执行阶段出现在类路径中。

我已经使用 M2E“依赖层次”视图确认范围是正确的。我已经尝试使用classpathDependencyScopeExcludein 选项maven-surefire-plugin来阻止依赖项出现，但它没有奏效：

<build>
  <pluginManagement>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-surefire-plugin</artifactId>
        <version>2.14.1</version>
        <configuration>
          <!--
            We always want to exclude provided deps. I'm not sure why this
            isn't the default.
          -->
          <classpathDependencyScopeExclude>provided</classpathDependencyScopeExclude>
        </configuration>
      </plugin>
    </plugins>
  </pluginManagement>
</build>

这是有问题的依赖定义：

父 POM：

<dependency>
  <groupId>javax.ws.rs</groupId>
  <artifactId>jsr311-api</artifactId>
  <version>1.1.1</version>
</dependency>

模块 POM：

<dependency>
  <groupId>javax.ws.rs</groupId>
  <artifactId>jsr311-api</artifactId>
  <scope>provided</scope>
</dependency>

罐子在那里正常吗？我该怎么做才能让它不出现？

编辑：我mvn dependency:tree在父 POM 上运行。这是相关项目的输出：

同样，具有提供范围的 jar 我希望不会出现在类路径上，但确实是 JAX-RS 规范 API，如上所示javax.ws.rs:jsr311-api:jar:1.1.1:provided。我相信这证实了这种依赖只出现在provided范围内。

编辑：如果我运行测试，这里是运行的命令行（来自ps）：

编辑：调查classpathDependencyScopeExclude文档后，我确定您只能排除compile,runtime和test依赖项，而不是provided. 这解释了为什么该功能不起作用。在尝试了下面@hello 的建议后，我确classpathDependencyExclude​​定直接使用 maven 运行时有效。这是我从surefire jar的清单中提取的类路径：

请注意，jsr311-api.jar 不存在。成功！这是有效的配置：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>${maven-surefire-plugin.version}</version>
  <configuration>
    <!--
      We never want to include these API deps on an execution classpath.
      I would think this is how the "provided" scope works - just
      compile against the jar, and then I'll bring it myself at
      execution time - but provided is only excluded during the runtime
      phase, not the testing phase. So, we have to exclude all our
      API JARs by hand.
    -->
    <classpathDependencyExcludes>
      <classpathDependencyExclude>javax.ws.rs:jsr311-api</classpathDependencyExclude>
    </classpathDependencyExcludes>
    <includes>
      <include>**/*Tests.*</include>
    </includes>
  </configuration>
</plugin>

但是，此解决方案似乎不适用于 M2E。ps这是我在使用 M2E 执行测试期间从 a 中提取的类路径：

不幸的是，jsr311-api.jar 仍然存在。这让我相信这个问题已经得到解答（答案是“使用classpathDependencyExcludes”），但 M2E 中有一个错误。我在 Eclipse 中运行了“检查更新”，但没有发现 M2E 的更新，所以我应该运行最新的稳定版本。我将在 M2E 上提交一个错误并在此处更新该问题，以便任何发现此问题的人都可以跟踪。

编辑： M2E已经提出了这个问题，答案似乎是“目前 Surefire 集成超出了 M2E 的范围。” 不鼓励。：/

鉴于provided范围的定义，我不希望该 jar 在任何执行阶段出现在类路径中。

这不完全是provided范围的行为。请参阅依赖范围。provided范围，与 相同compile，用于编译和测试您的类所必需的类。如果他们在此期间丢失，test那么您将拥有一个NoClassDefFoundError.

war不同之处在于打包和部署期间，在假设您的目标环境（例如，servlet 容器）将提供其自己的相同类的副本的情况下，从 s 中省略了这些工件。
