intellij idea - Java home path differs -

hello try execute project bootrun on intellij , followign error:

       execution failed task ':bootrun'.     > process 'command '/usr/lib/jvm/java-1.8.0-openjdk-    1.8.0.101-1.b14.fc24.x86_64/bin/java'' finished non-zero exit value 1 

i checked results of java paths , stuff , here there

         echo $java_home         /home/mypc123/downloads/jdk1.8.0_101/bin/java        $ java        /usr/bin/java 

i have jdk1.8.0 in /usr/bin

i looked more indepth , found this:

       error org.apache.tomcat.jdbc.pool.connectionpool - unable create initial connections of pool.       org.postgresql.util.psqlexception: fatal: role "syn12" not exist 

however when connect postgresql have syn12 role , gradle jvm's in form usr/lib/jvm/java.......

well got down : can't load library: /opt/symmetry/ste/java/libste-java.so ,how can install library?

seems have project jdk pointed installation. second issue different, incorrect jdbc url happens point another, existing, database schema in required role not exist.
