Eclipse IDE - Error: Build path specifies execution environment Java SE 1.7

Question

In Eclipse, I am getting an error:

Build path specifies execution environment Java SE 1.7.
There are no JREs installed in the workspace that are st

Answer 1

Go To Control Panel - check whether any new java version Updated -Uninstall it and Configure the Build Path JRE Library "Execution environment" to the Previous Version.

Probably if Java 7 is updated to Java 8 the above problem will occur. To avoid that warning, just you can uninstall the new update and restore the old version in execution environment.

Answer 2

Sounds like what I had after installing a newer Eclipse.

My solution:

Window->Preferences, Java->Installed JREs->Execution Environment.

Click the correct environment in the left panel, probably JavaSE-jre7

If the checkbox in the right panel is empty, check it.

If it's checked, but it isn't named jre7 [perfect match] then find the one in the left panel that does have 'perfect match' on the right and check that instead.
