upgrade eclipse to java 8

Question

I am trying to update my eclipse environment to java 8. I installed the jdk and jre version 8. I also did this:

https://wiki.eclipse.org/JDT/Eclipse_Java_8_Support_For_Kepler

then in project -> properties -> java build path -> JRE system libraries -> edit -> execution environment -> JavaSE-1.8(unbound) which is the only option that has java 8 in its name. but when I select it it says : No JREs in workspace compatible with specified execution environment: JavaSE-1.8

Answer 1

Go to Window | Preferences Window | Preferences . Then under Java | Installed JREs Java | Installed JREs , click "Add" , click "Standard VM" , then "Next" , then "Directory" , and find the location where you installed JDK 1.8 .

Lastly, make sure the checkbox next to it, on the list of installed JREs, is switched on.

Answer 2

In OS X, go to Preference and choose Java | Installed JREs Java | Installed JREs . Then click search it would show JAVA SE 8 if you have already installed JAVA SDK 8.

Answer 3

I would like to precise something. If you installed java8 with apt-get like me, the jdk is add to /usr/lib/jvm.
