“mvn --version”是：

Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 20:52:22+0530)

有人可以指导我吗？对此的任何帮助都将受到高度赞赏。谢谢！

【解决方案1】：

这似乎是由 Java 8 的 maven 错误引起的：

[MSHARED-319] Filtering throws NPE when using JDK8

一种解决方法是使用 Java 7。

【讨论】：

为什么这被否决了？这就是问题所在。我切换到 Java 7 并解决了问题。

【解决方案2】：

您需要使用最新的 maven-filtering 插件版本。如果错误是由使用 maven-filtering 作为隐式依赖的插件引起的，你应该声明它的依赖（例如 maven-remote-resources-plugin:

         <pluginManagement>
         <plugins>
         <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-remote-resources-plugin</artifactId>
            <version>1.5</version>
            <dependencies>
              <dependency>
                <groupId>org.apache.maven.shared</groupId>
                <artifactId>maven-filtering</artifactId>
                <version>1.2</version>
              </dependency>
            </dependencies>
         </plugin>
         </plugins>
         </pluginManagement>

我在从https://github.com/apache/parquet-mr 构建 Apache Parquet 时遇到了同样的错误，但是成功构建了 1.8.0rc1(https://github.com/apache/parquet-mr/archive/parquet-1.8.0rc1.zip)

【解决方案4】：

使用以下命令即可。

mvn install --batch-mode -DskipTests=true -Dmaven.javadoc.skip=true -Dsource.skip=true
