Before I compiled my code on Windows using eclipse ant and java 1.8 and it was fully working.

Now I am using compiling on Linux. I made sure to download jdk 1.8 and ant.

javac -version
javac 1.8.0_91

java -version
java version "1.8.0_91"
Java(TM) SE Runtime Environment (build 1.8.0_91-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.91-b14, mixed mode)

ant -v
Apache Ant version 1.7.1 compiled on April 26 2010

However, when I run ant to launch my build.xml, it is still failing from what seems to be wrong javac. Is there something else I need to set?

Buildfile: build.xml

    [javac] Compiling 12 source files to /build
    [javac] cannot access DBObject
    [javac] bad class file: Utilities.jar(DBObject.class)]
    [javac] class file has wrong version 52.0, should be 50.0
    [javac] Please remove or make sure it appears in the correct subdirectory of the classpath.
    [javac] import DBObject;

/build.xml:173: Compile failed; see the compiler error output for details.

When I do a ant -v

ant -v
