For example, Eclipse 2018-12 supports compilation of Java 11 and older versions even when you set to use JRE 14.Mac OS X: Installing Eclipse Mac OS X: Installing Eclipseĭownload the latest version of Eclipse fromĮclipse for RCP and RAP Developers, which is 249.8Mb. NOTES: The Java compiler compliance level you can set depends on the version of Eclipse’s internal compiler. Now, in the popup screen you can choose the execution environment for the JDK that supports the Java version you want to compile your project: Click Finish, and click Apply and close to apply compiler setting change and dismiss the project properties dialog. Now in the project properties dialog, navigate to the Java Build Path section: Select the JRE under Classpath and click Edit. And check the newly added JRE/JDK: Click Apply and Close. And in the next screen, click Directory to browse to JDK home or JRE home that supports the Java compiler version you want: Here, you can see I choose JDK 14 home directory. The next popup dialog appears: Make sure Standard VM is selected, and click Next. So click the hyperlink Installed JREs, which pops up the following dialog: Click Add button. To change version of Java compiler for your project, uncheck “ Use compliance from execution environment…”, the you can choose Java version from the dropdown list as below: Change compiler compliance level from 1.8 to 11 – you will see a warning from Eclipse: This warning means that no compatible JRE for Java 11 configured in Eclipse. 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.
