I've never seen this error before. My assumption is that it is related to the JDK you are using. I know the Oracle JDK/JRE 1.8 is ancient, but it works. I'm think you should be able to use OpenJDK 11, but I haven't tried this in a while.
Hi, I've experienced the same error in the last hour. I didn't understand how to solve it from this discussion so if everyone else will experience it and will come to this discussion- here's how to solve it:
It happens after you are deleting devices from the sdk manager that you have marked in one of your projects as a compatible device. to solve the problem, just download those devices again and refresh eclipse or go to manifest.xml file in every project, go to manifest.xml from overview in the bottom of the page and manually remove the line with the device you removed. for example, if I deleted the fr645 device from my sdk manager and I used it as a compatible device in my project, I'll go the file I've just mentioned and remove the line of <iq:product id="fr645"/>.
the problem should be solved after closing and saving the manifest.xml and refreshing the eclipse
I just had this issue, in my case there was a value fenix6pro in my manifest. Perhaps that was valid in an older SDK but replaced in newer. Anyhow i edited the manifest to remove this line and then things worked.
