我已成功使用AmpCamp的Spark版本来构建和运行几个项目。我现在正在尝试使用更新版本的Spark，1.2.1，但似乎无法构建它。
环境：
$ mvn --version
Apache Maven 3.0.5
Maven home: /usr/share/maven
Java version: 1.8.0_31, vendor: Oracle Corporation
Java home: /usr/lib/jvm/jdk1.8.0_31/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-45-generic", arch: "amd64", family: "unix"
$ echo $JAVA_HOME
/usr/lib/jvm/jdk1.8.0_31
$ echo $PATH
/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/usr/lib/jvm/jdk1.8.0_31/bin:/usr/lib/jvm/jdk1.8.0_31/db/bin:/usr/lib/jvm/jdk1.8.0_31/jre/bin:/usr/lib/jvm/jdk1.8.0_31/bin:/usr/lib/jvm/jdk1.8.0_31/db/bin:/usr/lib/jvm/jdk1.8.0_31/jre/bin
$ ant -version
Apache Ant(TM) version 1.9.3 compiled on April 8 2014
注意：尝试了“mvn -Pyarn -Phadoop-2.5 -Dhadoop.version = 2.5.0 -Dscala-2.11 -X -DskipTests clean package”，结果如下所示。
$ mvn -DskipTests clean package

我最初一直在JAVA_HOME中使用JRE。阅读帖子Error building Spark with Maven;遵循相同的建议，即使我没有找到javac的错误;但我仍然得到同样的错误。
建议??
使用-X output

答案 0 :(得分：1)
我卸载了maven和ant。 根据我们公司的配置安装了maven并配置了我的settings.xml，现在我可以构建spark。也许我本地安装的ant会导致问题，或者我安装的ant版本与pom.xml文件中的内容不匹配。
