title: IntelliJ IDEA 2017.2.5: Cannot determine embedded database driver
body: <p>Since some months I'm getting a lot of false positives when starting my Spring application in IntelliJ 2017.2.5. When starting it shows the error <code>Cannot determine embedded database driver class for database type NONE</code>. I just have to give it some additional tries and it will work. Often opening the <code>appliation.properties</code> in the IDE also helps (but might be coincidence). This happens to me (Linux) and also a friend working with the same project (Mac). Anyone else experienced that? </p>
