I understand, but how i can solve my problem? I try all variants of JAVA.

Delete all your JDK/JRE versions, and verify links to it under JAVA_HOME (google it). If you use a compiled pack (which you shouldn't), ask to whatever compiled it which JDK he used.

 

Once it is done, verify your JVM configuration on Eclipse.

 

You can also see current Java compliance of the project using alt + enter on your project > Java compiler > Compliance level.

usually you open build.xml and check what version needs to compile :) then install it, set JAVA_HOME in your computer environment variables to point at your JDK folder (google it) and then it will work also what tryskell said on your eclipse you need to also setup the jdk version to be used on build

Thank you guiys for all answer. +1 for all.
