I have a Java source code package which is known to successfully compile. I am attempting to compile the package with ant (the build.xml file is present). When I run ant all the Java import statements generate an error message of the type:
The import java.awt.geom.Path2D cannot be resolved" (the specific message depends on what is being imported)
Clearly the package paths are not defined and I have no idea where the requested imports live in the filesystem. I assume if I know the paths that setting $CLASSPATH will get the program to compile. I am using opensuse 13.2 and my installed java info is:
java -version
openjdk version "1.8.0_45"
OpenJDK Runtime Environment (build 1.8.0_45-b14)
OpenJDK 64-Bit Server VM (build 25.45-b02, mixed mode)
Can anyone point me to where to find the java packages and how to get ant to compile the sources?
The command line used to compile sources is: ant
build.xml is in the same directory that ant is run from which also contains the src directory. This is a working project, I just don't know how to configure standard library locations (I'm not a java type by any means).
Update.
I have located the path to the openjdk libraries at /usr/lib64/jvm/java-1.8.0-openjdk-1.8.0/jre/lib/rt.jar and have tried to compile 2 different ways but still get imports cannot be resolved error messages.
Compiling with -lib option does not work:
ant -lib /usr/lib64/jvm/java-1.8.0-openjdk-1.8.0/jre/lib/rt.jar
Setting the CLASSPATH environment variable does not work:
export CLASSPATH=/usr/lib64/jvm/java-1.8.0-openjdk-1.8.0/jre/lib/rt.jar
ant
The content of build.xml is:

Thanks!
Further update.
I added a classpath definition to the build.xml as below, still no joy. I have not used Java in many, many years so I am way out of my depth here, help desperately appreciated.
<property name="java.class.path" location="/usr/lib64/jvm/java-1.8.0-openjdk-1.8.0/jre/lib/rt.jar"/>
<target name="compile" depends="init">
<javac srcdir="${src.dir}" destdir="${build.dir}" debug="on"
includeantruntime="false">
<compilerarg value="-Xlint"/>
<classpath>
<pathelement path="${java.class.path}/"/>
</classpath>
</javac>
</target>
