When I download the eclipse for java, I found that I cannot run the eclipse.exe due to the “version 1.7 of the jvm is not suitable for this product. version 1.8 greater is required for eclipse neon in window”. I have installed the new java development kit in my D:/.
The reason is that we don’t specify the environment variable.
To solve this problem we just need add several environment variables in “System Variables”
To find the system variable: control panel –> System –> Advanced System Setting –> Environment varibles
Add the following varibles by adding “NEW” :
- Variable name : JAVA_HOME
- Variable value：C:\Program Files (x86)\Java\jdk1.8.0_91 (The path you installed the jdk)
- Variable name: CLASSPATH
- Variable value: .;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar; //don’t forget the “.”
- Variable name：Path
- Variable value：%JAVA_HOME%\bin;%JAVA_HOME%\jre\bin;
Then Reexecute your eclipse. The problem is probably resolved.
