Getting Error running javac.exe compiler message, while using Ant in Eclipse

Question

When I run my Ant build in Eclipse, I'm getting the following error message and the Ant build fails.

Error Message: Error running javac.exe compiler

Line where the build stops:

<javac destdir="${classes.home}" debug="on" fork="true" memoryinitialsize="512M" memorymaximumsize="1G">
        <classpath refid="classpath"/>
        <src path="${source.home}"/>
</javac>

Has anyone faced a similar problem before? or does anybody know what's wrong here?

System Information: Eclipse Helio, JDK 1.5

Answer 1

Maybe the javac problem is because "javac.exe" is not in your System PATH, please edit your system path and add your JDK's /bin directory to it to correct this problem.

Open a shell or command prompt and try typing: javac to check if the system path is set correctly.

Answer 2

Try changing memorymaximumsize="1G" to memorymaximumsize="512M".
