Oracle SQLDeveloper on MacOS won't open after installation of correct Java

Question

I downloaded the Oracle SQLDeveloper, but when I opened it, it said that it requires a minimum of Java 8 and gave me the website for the download. I went on and downloaded Java

Answer 1

I had the same problem, and none of the above solutions worked for me. I am running MacOS 10.14.5

Instead, I had to uninstall Java12 which I had installed via home brew, and sqlDeveloper. After uninstalling and deleting both, I installed Java8 JDK directly from the oracle website via download, and then I reinstalled sqlDeveloper. After wasting three hours trying to get this to work, this set of steps finally did the trick. I hope this helps others.
