The message seems to be out of date  In version 4 that setting exists in two files  and you need to change it in the other one  which is    APPDATA  sqldeveloper 1 0 0 0 0 product conf   Which you might need to expand to your actual APPDATA  which will be something like C  Users cprasad AppData Roaming  In that file you will see the SetJavaHome is currently going to be set to the path to your Java 1 8 location  so change that as you did in the sqldeveloper conf   SetJavaHome C  Program Files Java jdk1 7 0 60 bin    If the settig is blank  in both files  I think  then it should prompt you to pick the JDK location when you launch it  if you prefer

if you use sqldeveloper 18 2 0   edit  APPDATA  sqldeveloper 18 2 0 product conf   jdk9  jdk10  and jdk11 are not supported   change back to jdk 8   for example   SetJavaHome C  Program Files ojdkbuild java-1 8 0-openjdk-1 8 0 191-1

I cannot believe Oracle s documentation is SO LAME  In some documents it is misleading people to point to the JDK by specifying the path to the JDK root  e g  on a Mac        Library Java JavaVirtualMachines jdk1 8 0 151 jdk    Reviewing  Applications SQLDeveloper app Contents MacOS sqldeveloper sh revealed the method they use to set up the path      TMP PATH  usr libexec java home -F -v 9   if   -z   TMP PATH      then     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   Executing this manually from Terminal       usr libexec java home -F -v 1 8   Lists the path as    Library Java JavaVirtualMachines jdk1 8 0 152 jdk Contents Home   And this is what you need to specify as the value for      SetJavaHome  Library Java JavaVirtualMachines jdk1 8 0 152 jdk Contents Home   Thank you Oracle for wasting half a day on your  product  that does NOT even support your latest Java version  also released by you

For those who use Mac  edit this file    Applications SQLDeveloper app Contents MacOS sqldeveloper sh   Mine had   export JAVA HOME   usr libexec java home -v 1 7    and I changed it to 1 8 and it stopped complaining about java version

another thing you could try is to rename your old jdk folder  lets say its   C  Program Files Java jdk1 7 0 04  change it to saomething like   C  Program Files Java xxxjdk1 7 0 04  Now  you should once again asked to set your jdk folder location on Oracle SqlDeveloper launch  and you can chose the right path   Not the most elegant solution  but it worked for me   Milos

In your SQL Developer Bin Folder find   sqldeveloper bin sqldeveloper conf   It should be   SetJavaHome  path to jdk   You said it was       jdk originally so you could ultimatey do 1 of two things   SetJavaHome C  Program Files Java jdk1 7 0 60   This is assuming that you have JDK 1 7 60 installed in that directory  you don t want to point it to the bin folder you want the whole JDK folder   OR  The second thing you can do is find the jdk folder in the sqldeveloper folder for me its sqldeveloper jdk and copy and paste the contents from C  Program Files Java jdk1 7 0 60  You then have to revert your change to read  SetJavaHome       jdk   in your sqldeveloper conf  If all else fails you can always redownload the sqldeveloper that already contains the jdk7 all zipped up and ready for you to run at will  Download SQL Developer The file I talk about is called Windows 64-bit - zip file includes the JDK 7

On Windows Close all the SQL Developer windows  Then You need to completely delete the SQL Developer and sqldeveloper folders located in user AppData Roaming  Finally  run the program  you will be prompted for new JDK   Note that AppData is a hidden folder
