In the Properties dialog, navigate to Java Compiler section and you will see the following screen: To know Java compiler settings, right-click on the project and click Properties.
You can have your Eclipse running under JRE 11 but the project is compiled with JRE 8.Now, suppose that you have a project that is set to compile with Java 1.8. That’s why it’s not necessarily to have JDK to use Eclipse - just JRE is enough.Note that the JRE that runs Eclipse IDE is not necessarily the one that is used by Eclipse compiler. Instead, Eclipse uses its own internal compiler to provide more advanced features like incremental compilation – for quickly compiling only small changes you have made – not recompile the full project.And Eclipse compiler requires JRE to run its compiled. You can skip the steps 1 and 2 if your project is already configured with JRE/JDK that supports the Java version to which you want to change.Before going into each step in details, I think it’s worth to understand some background information first.You know, JDK provides the javac tool for compiling Java source code but Eclipse doesn’t use javac.
Now you want to upgrade the project to be compiled with Java 11.To summary, here are the steps to change Java compiler version for a project in Eclipse IDE: For example, you have to maintain an Eclipse project was developed at the time of Java 1.8.
In this post, I will show you how to change Java version used to compile a project in Eclipse IDE.
