If you check the download page (<a href="http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html" rel="nofollow noreferrer">http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html</a>) it says JDK8 required. I don't think it supports Java 9 or 10. Many programs still don't.

As for the command you tried it is for Windows, there is no c:\Program Files on MacOS. It should be enough to run <code>java -version</code>.

You may want to check how you can run multiple Java versions, see <a href="https://stackoverflow.com/questions/26252591/mac-os-x-and-multiple-java-versions">Mac OS X and multiple Java versions</a>. It is a bit messy, but sooner or later you will need it!

SQL Developer runs this which checks for java 9 then 8. We don't yet support (lack of a ton of testing) java 10. You went to new for us. Back up to 8 or 9 and should be fine.

We use <code>/usr/libexec/java_home</code> which allows us to specify which version of java we'd like to run. So even if you have N javas installed, it should return the highest one that was passed in with flags.

I have not tested this thoroughly, but at the very least I am able to bring up SQL Developer 19.1.0.094, connect to a database, and run queries on it. 

It did not work if I tried to use their instructions to install the "latest" version: <code>brew cask install adoptopenjdk</code>, as this seems to install OpenJDK 12.x as of May 2019. 

There are other methods to install OpenJDK, but this was an easy one.

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.

Previously, only JDK 8 worked with Oracle SQL Developer.

But, per <a href="https://www.oracle.com/tools/downloads/sqldev-v192-downloads.html" rel="nofollow noreferrer">https://www.oracle.com/tools/downloads/sqldev-v192-downloads.html</a>, JDK 8 or 11 are required. (there is some misleading documentation that says JDK 8 or higher, but it must be 8 or 11). Also, per Oracle, JDK 11.0.7 is certified for Mac OS Catalina.

JDK 11 certification: <a href="https://www.oracle.com/java/technologies/javase/products-doc-jdk11certconfig.html" rel="nofollow noreferrer">https://www.oracle.com/java/technologies/javase/products-doc-jdk11certconfig.html</a>

When I only had JDK 14 installed, it wouldn't run. It looked like it was going to, but wouldn't even start. You will need to give permission for it to run as it is still not an Apple approved app. (Ctrl-click, then Open, supposedly works &amp; saves your setting, but after so many changes trying to get this to work, I can't promise).

I had the same problem on Catalina 10.15.6 with SQLDeveloper 20.2.0 but none of the solutions mentioned here solved the problem. First I had to right click the SQLDeveloper.app file and choose &quot;Open&quot; as opposed to just double clicking to avoid the problem where it's not an Apple-approved app.
I tried installing various versions of the JDK and none worked until I tried JDK 11.0.8 (<a href="https://www.oracle.com/java/technologies/javase-jdk11-downloads.html" rel="nofollow noreferrer">https://www.oracle.com/java/technologies/javase-jdk11-downloads.html</a>). Looking at Applications/SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh as mentioned by Robert Bain helped. It's clear from that script that this version of SQLDeveloper will only accept JDK version 1.8, 11, or 12.
Once I had JDK 11 installed, the install worked as expected.

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 10.0.1, but when I went back on to open SQL, it continued saying it required a minimum of Java 8.

I checked that the Java 10.0.1 had installed correctly, and I'm pretty sure it has. It shows up in System Preferences and when clicked, it opens the Java Control Panel fine.

I had also found someone recommending trying this command:

<pre><code>c:\Program Files\Oracle\sqlcl\17.3\sqlcl\bin&gt;java -version
</code></pre>

After trying this in the Terminal, I ended up with <code>command not found</code>.
