我已经从“ https://github.com/apache/flume/downloads ”下载了flume ..但是我无法构建它..我需要先安装thrift才能构建flume吗？如果是这样，什么是共振..当我运行 mvn compile 时出现以下错误 -

Flume 有一些代码生成，它利用 thrift 作为传输通信序列化机制。

在 flume-core/pom.xml 中，你可以看到：

<plugin>
    <groupId>org.apache.thrift.tools</groupId>
    <artifactId>maven-thrift-plugin</artifactId>
    <version>0.1.10</version>
    <configuration>
      <thriftExecutable>${thrift.executable}</thriftExecutable>
    </configuration>
    <executions>
      <execution>
        <goals>
          <goal>compile</goal>
          <goal>testCompile</goal>
        </goals>
      </execution>
    </executions>
</plugin>

需要安装thrift，然后在父pom.xml中配置位置：

<properties>
  <!-- NB: The version of the thrift compiler must match that of the dependency 
  on the jar file below. -->
  <thrift.executable>${env.THRIFT_HOME}/bin/thrift</thrift.executable>

  <!-- Set default encoding to UTF-8 to remove maven complaints -->
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

  <!-- defaults for flaky test and focused test exclusions -->
  <test.exclude.pattern>$</test.exclude.pattern> <!-- junk pattern -->
  <test.include.pattern>**/Test*.java</test.include.pattern>
</properties>
