You can choose to ignore this problem or set it to Info by changing its severity level on the Java Compiler preference page: When a preview feature is used in the code, a default warning is provided by the compiler that the preview feature may not be supported in a future release. To quickly enable the preview features on an existing Java project, you can right-click on it in the Package or Project Explorer and select Configure > Enable preview features: Then, set the JDK compliance in Preferences > Java > Compiler:
To get started, you can add a JRE in Preferences > Java > Installed JREs: Here is a sneak peek into the major interesting features of recent Java versions with their support in the Eclipse IDE. To support the latest Java versions, the Eclipse Compiler for Java implements all the new language enhancements, existing tooling support is updated to blend with the new language features, and new functionality is added to help you while working with the new language constructs. The Java tooling in Eclipse IDE has its own compiler implementation which not only generates class files, but also produces a Java document model which forms the basis for implementing a large number of tooling features. To give them a spin, you have the tooling support in Eclipse Java IDE ready at your disposal. Every new release of Java promises interesting features and updates. With faster Java releases, it’s an exciting time to be a Java developer. The Java language has been evolving at a fast pace with a six month release cadence and preview features. She co-leads the Eclipse Java Development Tools project and is a member.
