Features to show

• IDE packages for additional platforms 📽️:
  • Windows on ARM (supported by the Eclipse platform since the last release and now also by OpenJDK/Eclipse Temurin)
  • Linux on RISC-V (supported by the Eclipse platform since this release; longer supported by OpenJDK/Eclipse Temurin)
• Java📽️
  • Java 23 support (but IDE packages shipped with Java 21, the latest LTS version)
    • JEP 467: Markdown Documentation Comments, including rendering in hover and Javadoc view
    • Preview features:
      • JEP 476: Module Import Declarations (Preview), e.g. import module java.desktop; (with that, type import statements are only needed for ambiguous simple names, like java.util.List vs. java.awt.List)
      • JEP 482: Flexible Constructor Bodies (Second Preview): In constructors, super(...) no longer needs to be the first statement
      • JEP 477: Implicitly Declared Classes and Instance Main Methods (Third Preview): void main() { println("Hello, World!"); } is a minimal and complete "Hello, World!" application
  • Java editor
    • New warning: Unnecessary code > Value of lambda parameter is not used (22 or higher) with corresponding quick fix to configure its problem severity
    • New quick fix: Rename to unnamed variable: when using Java 22 or above (see also corresponding clean-up bellow)
  • Clean-ups
    • Enhanced: Unnecessary Code > Unused code > Remove unused local variables: to rename to unnamed variable (_) where possible and when using Java 22 or above (unused lambda parameters, try-with-resources resources, pattern variables in switch and variables in enhanced as well as in regular for statements)
    • New: Code Style > Control statements > Simplify boolean if/else to single return if possible: if (...) { return true; } else { return false; } → return ...;
    • (Enhanced: Code Style > Control statements > Convert if/else if/else chain with 3 blocks min to switch to properly handle cases where the value can be null: Java 20 and lower (if (... != null) { switch (...) { ... } } else { ... }) vs. Java 21 and higher (case null: ... thanks to JEP 441))
  • Call Hierarchy view: new filter button with new option to show test code only (Filter Test Code became Hide Test Code or Test Code only)
  • Performance
    • (Faster Project > Clean... via BatchImageBuilder: write .class files in batches)
    • (Avoid reading SourceFile twice)
    • (In the preferences Java > Installed JREs > Execution Environments, faster switching of the JRE (via Share JRT entries across projects and Faster ExecutionEnvironmentsPreferencePage.performOk()))
  • (Maven)
  • Gradle 📽️
    • Problems API integration: disabled by default; can be enabled in the preferences Gradel > Experimental features: Enable Problems API support, e.g. to get problem messages from javac, but not e.g. from this Modernizer Gradle plugin (experimental; see also commit)
    • (Syntax highlighting in the compare editor for build.gradle files)
• General/Platform 📽️
  • Text editors

    • (Delete Files of Directories in parallel)
    • (Improve performance for large selection)
• (Git)
• Web 📽️
  • TypeScript 5.7 support
  • JavaScript/TypeScript tooling (in JavaScript enable validation via // @ts-check):
    • Correct override checks on computed properties (override in JavaScript via JSDoc: /** @override */)
    • Checks for never-initialized variables (TypeScript only)
• (Under development)
  • (Initiative 31: Prototyping work for candidate technology evaluation on Eclipse SWT)
  • (JDT to support javac instead of ejc driven by jdtls: incubator)
  • (Gradle: Kotlin DSL support: build.gradle.kts (does not work on Windows yet))
  • (Debug: show values inline (not yet supported in Java, JavaScript, etc.))
  • (Run/Debug As > ... right-click menu directly shows available launch configurations_: supported by JDT?)
