我在学习maven时遇到了这个报错，找到了这位外国友人写的博客。
http://www.kriblog.com/ide/sts/error-no-compiler-is-provided-in-this-environment.-perhaps-you-are-running-on-a-jre-rather-than-a-jdk.html
他提供了三种方法：
第一个修改jre的我自己试过好像没用；
第二个据说是最好的方法然而我还没接触Spring，因而作罢；
第三个亲自试验确实可行，然而却不能一劳永逸。
也希望有高手能来指点迷津。。

对我来说今天真是糟糕的一天，我花了许多时间下载最新的 Spring Tool Suite based on Eclipse 4.4.1 压缩版，但是现在出现了下面的错误。

[ERROR] COMPILATION ERROR :[INFO] -------------------------------------------------------------[ERROR] No compiler is provided in this environment.

有人知道这个问题吗？先提前感谢一下。

你可以选择以下任意方式解决[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

方法1

点击 Windows -> Preferences -> Java -> Installed JREs -> Add -> Standard VM，然后选择JAVA_HOME
从已经安装的JRE中选择新的JRE并点击OK

方法2

最简单并且在所有场景中都适用

第一步-打开Spring Tool Suite(STS)的安装目录
第二步-右击STS.ini
第三步-打开 -VM JAVA_HOME/bin/javaw.exe然后重启Eclipse Spring Tool Suite (STS)，Eclipse将会自动获得这个JDK

 -vmG:/jdk1.7.0_25/bin/javaw.exe-startupplugins/org.eclipse.equinox.launcher_1.3.0.v20140415-2008.jar--launcher.libraryplugins/org.eclipse.equinox.launcher.win32.win32.x86_1.1.200.v20140603-1326-productorg.springsource.sts.ide--launcher.defaultActionopenFile--launcher.XXMaxPermSize256M-vmargs-Dosgi.requiredJavaVersion=1.6-Xms40m-Xmx768m-XX:MaxPermSize=256m-Dorg.eclipse.swt.browser.IEVersion=10001

方法3

打开pom.xml，输入以下高亮部分并将正确的JDK路径输入。(不支持部分高亮，start至end部分)

<build>    <plugins>        <plugin>            <groupId>org.springframework.boot</groupId>            <artifactId>spring-boot-maven-plugin</artifactId>        </plugin>        <!--start-->        <plugin>            <artifactId>maven-compiler-plugin</artifactId>            <version>3.1</version>            <configuration>                    <fork>true</fork>                       <executable>                       D:\jdk1.7.0_25\bin\javac.exe                      </executable>            </configuration>        </plugin>        <!--end-->    </plugins></build>

祝你好运！
