我想改变使用sun jdk打开jdk的maven java home.我该怎么做 ？

root@ak-EasyNote-TM98:~# mvn -version
Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.6.0_24, vendor: Sun Microsystems Inc.
Java home: /usr/lib/jvm/java-6-openjdk-amd64/jre
Default locale: tr_TR, platform encoding: UTF-8
OS name: "linux", version: "3.2.0-34-generic", arch: "amd64", family: "unix"

Edit:

非常抱歉.我忘了写下面的代码:

root@ak-EasyNote-TM98:~$ java -version
java version "1.7.0_07"
Java(TM) SE Runtime Environment (build 1.7.0_07-b10)
Java HotSpot(TM) 64-Bit Server VM (build 23.3-b01, mixed mode)

我的java home默认路径已经是sun jdk了.但maven java home指向openjdk.我想只为maven修复它.

运行我们的Maven构建时,我的团队成员在执行时会收到此错误.但是,当我们java -version从她的命令行运行时,它表示Java 1.6.0_26.Maven正在使用Java 5,这个错误显然似乎在尖叫.

我如何找出并更改Maven正在使用的Java版本？

3个可能重要的说明:

1. 这是在命令行执行的,而不是使用Eclipse插件
2. JAVA_HOME设置为Java 1.6 JDK
3. 使用Maven 2.2.1

由于scala 2.9.2项目与java 8版本之间不兼容,我需要在我的maven项目中手动指定jvm用法.

pom.xml中我做,用文档在这里:

我正在尝试下载并安装这个 Maven 插件：

https://github.com/mirkonasato/graphipedia

我cd在目录中并运行

mvn clean install

我今天在 Mac 上使用 homebrew 安装了 mvn，所以它应该是最新的。我收到的错误是：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project graphipedia-dataimport: Compilation failure
[ERROR] error: Exception thrown while constructing Processor object: org/neo4j/kernel/impl/annotations/ServiceProcessor : Unsupported major.minor version 51.0

我用 google 搜索了这个错误，发现有几个人说，原因可能是旧的 Java 版本。所以我检查了我的系统偏好设置，它显示 Java 7。

但我真的不相信这一点并跑了

mvn --version

这给了我这个输出
