Modifying JDK versions in eclipse

In Eclipse, a Java project relies on a JDK that needs to be bound, but there are multiple places to bind, similar to the hierarchy.

1. Java compiler, Preferences, window, eclipse Equivalent to a top-level binding. Default

2. Right-click on each project, properties---project facets, types of bound projects;

3. Right-click on each project, properties, Java compiler, bind the project-level compiler type;

4. Right-click on each item project, build path, JRE runtime;

5. Or a MAVEN project, the compiler-plugin of the MAVEN project will also let you specify the compiler model.

So, check the order, which is bound by the top down, in turn.

When binding multiple versions of the JDK in one eclipse, it's good to do it at the specific project level .
