问题描述

在编译Maven项目时，发生以下错误:

While compiling the Maven project the following error occured:

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

我从pom.xml中删除了属性<useZincServer>true</useZincServer>，但仍然记录错误.

I removed the property <useZincServer>true</useZincServer> from pom.xml, and still the Logging error persists.

我检查了~/.bashrc中是否定义了PATH和JAVA_HOME，如下所示:

I checked that PATH and JAVA_HOME are defined in ~/.bashrc as follows:

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，尽管我做了source ~/.bashrc，但echo $JAVA_HOME却给出了空的输出​​.

The only issue that I noticed is that echo $JAVA_HOME gives an empty output, though I did source ~/.bashrc.

我们非常感谢您的帮助.

Any help is highly appreciated.

推荐答案

问题可能出在[INFO] Using incremental compilation

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

In your pom.xml try to remove the line
<recompileMode>incremental</recompileMode>
and then try again.
