Question

在ubuntu上编译Hive期间我运行此命令。

    $ git clone https://git-wip-us.apache.org/repos/asf/hive.git
    $ cd hive
    $ mvn clean package -Pdist

然后我得到这个错误

    [INFO] Reactor Summary:
    [INFO]
    [INFO] Hive .............................................. SUCCESS [5.461s]

    [INFO] Hive Accumulo Handler ............................. SKIPPED

...

    [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hive-exec: Compilation failure

如何修复此错误可以帮助我！

Answer 1

Maven编译器插件内存不足。您可以为root pom.xml中的编译器插件配置进行以下更改，从而为其分配更多内存。

在第738行

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>${maven.compiler.plugin.version}</version>
  <configuration>
    <source>1.7</source>
    <target>1.7</target>
    <jvmArgs>-Xmx2048m -Xms512m</jvmArgs><!--increasing memory-->
  </configuration>
</plugin>

我已将其设置为2GB，这可能有点矫枉过正，但先尝试一下。还可以使用以下命令尝试在没有测试的情况下运行构建。

mvn clean package -Pdist -Dmaven.test.skip=true

-Dmaven.test.skip将跳过运行测试用例并更快地生成构建结果。

Answer 2

当我没有指定Hadoop版本并使用此命令跳过测试用例时构建成功：

mvn clean package -DskipTests

编译Hive mvn clean包时出错-Pdist
