Answer 2

For me (on windows 10), I was getting the error "No compiler is provided in this environment" at the Windows command prompt when I ran mvn install. The fix was changing the JAVA_HOME environment variable to point to my jdk (C:\Program Files\Java\jdk1.8.0_101); previously it had pointed to the jre.

And to get Eclipse to use the new jdk, I edited eclipse.ini in my eclipse distribution and changed the line for -vm to C:\Program Files\Java\jdk1.8.0_101\bin.

This worked for me. 1. Click on Window-> Preferences -> Installed JRE. 2. Check if you reference is for JDK as shown in the image below.

If not, Click on Add-> Standard VM -> Give the JDK path by selecting the directory and click on finish as shown in the image

3. Last step, click on Installed JREs -> Execution Environments -> select your JDE as shown in the image below

4. Maven -> Clean

Answer 4

if someone is running Eclipse in Ubuntu and have this problem I have found the answer by following these steps:

1. Eclipse->window->preference.
2. Select installed JREs->Add
3. Select standardVM.
4. JRE home: press [Directory..] button.
5. Choose your java (my problem was my eclipse was running with java8 and my VM were with java7), in my case java8 was installed in usr/local/jvm/java-8-oracle.
6. Press finish.
7. Then press installed JRES arrow so you can see the other options.
8. Go to Execution Environment.
9. Select JavaSE-1.6 on left and in the right (the compatible JRE) you have to choose the Java you have just installed( in my case java-8-oracle). you have to do this steps with JavaSE1.8.
10. Click OK and restart Eclipse.
