Groovy Eclipse plugin contributes to "Invalid registry object" at Eclipe start

[davidmichaelkarr]

For a long time now, I've been annoyed by the symptoms described in this Eclipse bug report that I created: https://bugs.eclipse.org/bugs/show_bug.cgi?id=528462 .

Today I realized that if I don't have the Groovy Eclipse plugin installed, this doesn't happen. I've now tried going back and forth, verifying that it only happens when I have that plugin installed. I verified this with the same version of Eclipse, but on two different computers (ok, a Windows laptop and a Linux VM running on that laptop).

I also have a bunch of other plugins installed, so this could very well be a subtle plugin interaction problem, but it's at least related to this.

This sounds like a familiar old issue that cropped up with Oxygen and went away quietly. Do you have multiple Groovy Compiler versions installed? Are you running with the latest Eclipse Oxygen and Groovy-Eclipse versions?

[eric-milles]

You can look to #317 for reference. There were some fixes realized for Oxygen.

I do have multiple compiler versions installed. I'm using the latest Oxygen and latest Groovy eclipse version. I looked through the history of that issue, but I'm unsure what the workaround is. Is the point to remove all but the newest compiler version?

If you remove all compiler versions except the one you use, there will be no hot-swapping during startup.

Can you say the version numbers of Eclipse and Groovy-Eclipse? Or you could send a copy from the installation details dialog.

4.7.3a and 3.0.0.xx-201804112146-e47 , but reinstalling with only the 2.4 compiler has fixed this problem. I no longer get the registry error on start.

How do you reinstall only the 2.4 compiler?

[eric-milles]

@xenonrider You can install the Groovy Compile 2.4 feature and remove the Groovy Compiler 2.5 feature.
