In my Mac terminal:

$ javac -version
javac 10.0.1

I open SQL Developer and get this dialog:

SQL Developer requires a minimum of Java 8. Java 8 can be downloaded from: http://www.oracle.com/technetwork/java/javase/downloads/

The dialog image

How do I get SQL developer to work?

  • Could be a simple system variable path issue. – Ramhound Jun 20 '18 at 01:31
  • I download java sdk 8 at http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html and now sql developer works – Henry Yang Jun 20 '18 at 01:33
  • maybe you had OpenJDK, while OracleJDK was required? (see [this](https://stackoverflow.com/a/51714163/2147927) comment) – Line Aug 29 '19 at 14:06
  • @Line Sorry my SQL developer works now and I don't remember what I did to fix it. I should have posted my solution when I fixed it. I will just leave this question open if other people encounter same issue – Henry Yang Aug 30 '19 at 01:50

If you don't still want to keep java 10, the fix is easy

vi /Applications/SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh

Change the second line:

From: 

TMP_PATH=`/usr/libexec/java_home -F -v 9`

To 

TMP_PATH=`/usr/libexec/java_home -F -v 10`

Had the same issue. Installed SQL Developer 18.2.0.183 with JDK 10.0.1 and had this message:

Found /usr/java/jdk-10.0.1/bin/java/bin/java to run this product, and the major version of this Java is 10.The mandatory minimum major version to run this product is 1.8.

Once I removed the 10.0.1 version and installed the 1.8.0_172 version it worked fine.
