编译Maven项目时发生以下错误：

[INFO] --- scala-maven-plugin:3.2.2:compile (scala-compile-first) @ spark-streaming-flume-sink_2.10 --- 
[WARNING] Zinc server is not available at port 3030 - reverting to normal incremental compile

我从pom.xml中删除了属性<useZincServer>true</useZincServer>，但仍然存在Logging错误。

我检查了PATH和JAVA_HOME在~/.bashrc中的定义如下：

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echo $JAVA_HOME提供了空输出，但我做了source ~/.bashrc。

非常感谢任何帮助。

Answer 1

奇怪的回声$ JAVA_HOME给出了一个空输出。在编译Spakr Source时，我将mvn clean package成功导入eclipse，我遇到了同样的问题。我在这里找到了解决方案： How to solve “Plugin execution not covered by lifecycle configuration” for Spring Data Maven Builds

Answer 2

我认为你正在使用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

希望这有帮助。

Answer 3

问题可能是[INFO] Using incremental compilation

在你的pom.xml中尝试删除行<recompileMode>incremental</recompileMode>
然后再试一次。

无法执行目标net.alchim31.maven：scala-maven-plugin：3.2.2
