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 have the same problem with MacOS Big Sur, Java 8. Clicking on the icon doesn't work. This command from terminal starts the application. sh /Applications/SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh This stopped working in MacOS Big Sur 11.2

Answer 2

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 /usr/libexec/java_home 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.

   #!/bin/bash 
              ##### THIS IS CHECKING FOR JAVA 9 #####
   TMP_PATH=`/usr/libexec/java_home -F -v 9`

   if [ -z "$TMP_PATH" ] ; then

              ##### THIS IS CHECKING FOR JAVA 8 #####
     TMP_PATH=`/usr/libexec/java_home -F -v 1.8`

     if [ -z "$TMP_PATH" ] ; then
       osascript -e 'tell app "System Events" to display dialog "SQL Developer requires a     minimum of Java 8. \nJava 8 can be downloaded from:\n http://www.oracle.com/technetwork    /java/javase/downloads/"'
       exit 1
     fi
   fi

Working solution for Mac running macOS Catalina 10.12.5 with openjdk 11 and SQLDeveloper 19.4.0.354:

Edit /Applications/SQLDeveloper.app/Contents/MacOS/sqldeveloper.sh:

1. Delete all the code before export JAVA_HOME=$TMP_PATH
2. Change export JAVA_HOME=$TMP_PATH to export JAVA_HOME=<path_to_jdk>/jdk-11.jdk/Contents/Home
3. Start SQLDeveloper

If macOS complains about the files being downloaded from the internet call xattr -d com.apple.quarantine <filename>.

Incidentally I saw /Applications/SQLDeveloper.app/Contents/Resources/sqldeveloper/sqldeveloper/bin/jdk.conf has instructions for setting the java home by uncommenting and specifying SetJavaHome but that didn't work for me.

Answer 4

If you check the download page (http://www.oracle.com/technetwork/developer-tools/sql-developer/downloads/index.html) 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 java -version.

You may want to check how you can run multiple Java versions, see Mac OS X and multiple Java versions. It is a bit messy, but sooner or later you will need it!

Answer 5

If OpenJDK would work for you, and you are already using/willing to use Homebrew, AdoptOpenJDK works for me:

brew tap AdoptOpenJDK/openjdk
brew install adoptopenjdk8

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: brew cask install adoptopenjdk, 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.

Answer 6

You have to set the Java home. Please follow the steps given below.

• find the installation directory by right-clicking the OracledataModeler icon and "Show Package Content" this will show you the installation directory on a Mac

• Go to the (installation directoy for example ) /Users/user directory/Downloads/OracleDataModeler.app/Contents/Resources/datamodeler/datamodeler/bin

• edit the datamodeler.conf file in the \datamodeler\datamodeler\bin directory and add SetJavaHome. (e.g. SetJavaHome /usr/lib/jdk18)

• SetJavaHome /Library/Java/JavaVirtualMachines/jdk1.8.0_221.jdk/Contents/Home

• Start the SQL data modeler from (installation directory) /Users/user directory/Downloads/OracleDataModeler.app/Contents/Resources/datamodeler/datamodeler.sh
