Intellij IDEA: Driver class 'com.dbschema.MongoJdbcDriver' is incompatible with current JRE

Question

I was getting this error after clicking the test connection button for a MongoDB connection in the IntelliJ IDEA Database tab:

enter image description here

Driver class 'com.dbschema.MongoJdbcDriver' is incompatible with current JRE.

It took me over an hour to fix this because there were literally no results when I googled for the exact search term.

There are multiple ways to fix this error, which I'll post below.

Answer 1

For some reason, my IntelliJ IDEA (the IDE itself, not my code) was bootstrapped from JDK 17. Using a newer version fixed the error. Here's how I did that:

1. Go to Help -> Find Action

2. Type "Choose Boot Java Runtime for the IDE"

3. Select a newer Java version. I chose Java 21:

4. IntelliJ will ask you to restart. Click Okay.

5. The Driver class 'com.dbschema.MongoJdbcDriver' is incompatible with current JRE error went away and I was able to successfully connect.

Obviously that warning in step 3 is pretty suspicious. It doesn't bother me because I'm just trying to get past this, and I'll be setting up a new computer in a few days.

Alternatively, you could use a different MongoDB driver than the one that comes with IntelliJ IDEA, but I tried and ran into different connection problems with that.

I could have tried using an older version of the IntelliJ IDEA MongoDB driver until it was compatible with the IntelliJ IDEA runtime, but I didn't go down that route myself. I can't guarantee it'll solve the problem.
