编译 Maven 项目时出现以下错误：

[INFO] --- scala-maven-plugin:3.2.2:compile (scala-compile-first) @ spark-streaming-flume-sink_2.10 ---

我<useZincServer>true</useZincServer>从 pom.xml 中删除了该属性，但日志记录错误仍然存​​在。

我检查PATH并JAVA_HOME定义~/.bashrc如下：

export PATH=$PATH:/usr/lib/jvm/java-7-openjdk-amd64/bin
export JAVA_HOME=/usr/lib/jvm/java-7-openjdk-amd64

我注意到的唯一问题是它echo $JAVA_HOME给出了一个空输出，尽管我做了source ~/.bashrc.

非常感谢任何帮助。

问题可能是这个[INFO] Using incremental compilation

在您的 pom.xml 中尝试删除该行
<recompileMode>incremental</recompileMode>
，然后重试。

我认为您正在使用 Scala 2.10 编译 Spark。如果是这样，您应该执行以下操作。

cd /path/to/Spark
./dev/change-scala-version.sh 2.10
./build/mvn -Pyarn -Phadoop-2.4 -Dscala-2.10 -DskipTests clean package

希望这可以帮助。

奇怪的是 echo $JAVA_HOME 给出了一个空输出。在编译 Spakr 源时，我将 mvn clean 包成功项目导入到 eclipse 中，我遇到了同样的问题。我在这里找到了解决方案： 如何解决“插件执行未覆盖Spring Data Maven 构建的生命周期配置”
