I tried all the things  the one that worked for me is    Right click on Eclipse project and navigate to properties  Click on Java Build Path and go to the Libraries tab  Check which version of Java is added there   is it JRE or JDK  If you are using Maven project and want to build a solution  Select the JRE added their and click remove  Click Add external class folder and add the JDK install by selecting from the system  Click Apply and OK  Restart Eclipse  Build succeeded

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

To check what your Maven uses  open a command line and type   mvn    version   Verify that JAVA HOME refers to a JDK home and not a JRE  On Windows   Go to System properties -  Advanced system settings -  Advanced -  environment variable and on the System variables section select the JAVA HOME variable and click on Edit Fill the form with the following Variable name  JAVA HOME Variable value    On Unix   export JAVA HOME  lt ABSOLUTE PATH TO JDK gt    see this link

Please check if you have the following entries in the  element of your pom xml especially the jdk version because switching to an installed jre did not fix me the similar error    lt properties gt       lt jdk version gt 1 7 lt  jdk version gt       lt spring version gt 4 1 1 RELEASE lt  spring version gt       lt jstl version gt 1 2 lt  jstl version gt       lt junit version gt 4 11 lt  junit version gt   lt  properties gt

I also faced similar error when I was working with Jdk1 8 92  For me  I found tools jar was missing in my jdk folder  Since I was running in console  I couldn t try the options of eclipse suggested by others    I installed jdk-8u92-windows-x64   After I tried all options  I observed that tools jar was missing in jdk1 8 0 92 lib folder   I copied tools jar from my older version of java  Then It was able to compile

if you are working outside of eclipse in the command window make sure you have the right JAVA HOME and that that directory contains the compiler by entering the following command in the command window   dir  JAVA HOME  bin javac

In my case  I had created a run configuration and whenever I tried to run it  the error would be displayed  After searching on some websites  I edited the run configuration and under JRE tab  selected the runtime JRE as  workspace default JRE  which I had already configured to point to my local Java JDK installation  ex  C  Program Files  x86  Java jdk1 8 0 51   This solved my issue  Maybe it helps someone out there

I had a problem with Eclipse Neon where the workspace default did not actually change even though I added the correct location under Preferences- Java- Installed JREs  This was in a new workspace I created to work on a code branch  it was originally set to the JRE location rather than the JDK  Yet even after changing the preferences  I could build with the command line  yet building in Eclipse produced the no compiler error  Please see  Maven Package Compilation Error  for my answer on which Eclipse configuration file s  had to be manually edited to make Eclipse recognize the correct workspace default  I still have no idea why the preferences setting did not carry through to the new workspace s configuration
