Maven 错误:也许您在 JRE 而不是 JDK 上运行? [英] Maven error :Perhaps you are running on a JRE rather than a JDK?

问题描述

我以前从未使用过 Maven，我正在按照说明操作 此处. 当我运行命令时

I've never worked with Maven before and I am following the instructions here. When I run the command

mvn integration-test -Pamp-to-war

最初下载了一大堆依赖，最后显示，

It initially downloaded a whole bunch of dependencies, and in the end it showed,

COMPILATION ERROR : 
[INFO] -------------------------------------------------------------
[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?
[INFO] 1 error

我使用的是 ubuntu 13.04.

I am on ubuntu 13.04.

如果你有什么想让我告诉你的，请告诉我.谢谢.

If there's anything you want me to tell you, let me know. Thanks.

编辑

当我执行 echo $JAVA_HOME 我得到 /usr/lib/jvm/java-7-openjdk-i386/

当我做 mvn -version

我明白了，

Apache Maven 3.0.4
Maven home: /usr/share/maven
Java version: 1.7.0_25, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-7-openjdk-i386/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.8.0-26-generic", arch: "i386", family: "unix"

另外，我发现了其他人面临的这个问题.但我不确定如何执行指定的解决方案?

Also, I found out this problem faced by someone else. But I am not sure how to go about the solution that is specified?

推荐答案

显然，它需要我的 $JAVA_HOME 的 lib 文件夹中的 tools.jar 文件.我没有 lib 文件夹，所以我使用命令

Apparently, it requires tools.jar file inside the lib folder of my $JAVA_HOME. I did not have the lib folder, so I reinstalled my jdk using command

apt-get install openjdk-7-jdk openjdk-7-doc openjdk-7-jre-lib
