Eclipse. Installing STS4 causes Eclipse update error on Wild Web Developer XML Tools

Question

I did a clean install of Eclipse. After installing the Spring Tools Suite 4 I get an error when checking for Eclipse updates. Any suggestions?

• Deleted ~/{.eclipse,.p2,.sts4,eclipse,eclipse-workspace}
• Installed Eclipse Temurin OpenJDK - jdk-17.0.4.1+1 Windows x64
• Installed Eclipse 2022-06 Windows x86_64
• Help > Check for Updates
  • No updates found
• Help > Eclipse Marketplace
  • Installed tab is empty
• Installed "Spring Tools 4 (aka Spring Tool Suite 4) 4.15.3.RELEASE
  • Confirmed default selected features
• Restart
• Help > Check for Updates
  • Cannot complete the install because one or more required items could not be found.
    • Wild Web Developer XML tools 0.14.0.202206022022

Answer 1

I can reproduce this and I am still a bit puzzled about why this happens, but you can solve this by adding an additional update site to your Preferences -> Install/Update -> Available Update Sites:

https://download.eclipse.org/wildwebdeveloper/releases/0.13.6/

Once that update site is around, the Check for Updates can complete.
