Known limitations

  • JDK8/9/10/11:

  • JDK required instead of a JRE

    • Some features of the tooling (e.g. the live hover information) require you to run the tooling on top of a JDK instead of a JRE. So please take care to configure your Spring Tools 4 Eclipse installation with a JDK instead of a JRE. You can find the instructions here: https://wiki.eclipse.org/Eclipse.ini
    • the same applies to the extensions for Visual Studio Code and Atom, so make sure you have your JAVA_HOME point to a JDK instead of a JRE.

  • Windows

    • If "Live Boot Hints" not showing up when they are supposed to check if <User-Temp-Folder> has file hsperf-<username>. If yes, delete this file and restart your boot app and STS4 (Eclipse, VSCode or Atom).

  • Lombok

    • The Lombok installer doesn't know about the changed name of the STS4 executable and therefore doesn't find it. Nevertheless you can install Lombok manually by modifying the SpringTools4.ini file yourself.

  • Live Hovers not showing up

    • make sure the Spring Boot Actuators are on the classpath (add the Maven dependency, if necessary)
    • make sure your project is either Boot 1.5.x, Boot 2.0.x, or Boot 2.1.x.
    • make sure you run on a JDK, not a JRE (see above)
    • there are some network configuration cases that prevent the language server from connecting to the running Spring Boot application via JMX. In that case, add -Djava.rmi.server.hostname=localhost to the VM arguments when starting up your Spring Boot app.
    • On Windows... it is fairly common for the folder at %TMP%\hsperf-%USERNAM% to get wrong permissions, especially if you recently installed / reinstalled or updated your JDK. To fix this, simply delete the folder and restart your Boot app and STS 4 (Eclipse, VSCode or Atom). The next java process you start should recreate the folder with correct permissions.

  • Navigation inside of live hovers broken in Atom

    • the navigation to bean definitions and types from within live hovers shows up, but doesn't work when clicking on the links, this is a known bug and we are working on it
