Hi,
My problem is I am getting out of memory error when I try to compile java
files( around 1200 ) to create a jar.
I have some questions...
* First time , when I tried to compile the java sources using ant, I got
following error.
[javac] Compiling 1162 source files to
/sapphire/users/sapbuild/ENV2/online/BUILD/sap_jar_input
[javac] The compiler has run out of memory. Consider using the
"-J-mx<number>" command line option to increase the maximum heap size.
Imp point : If I compile the sources using javac -J-mx1000000000 -d
$TEMP_SOURCE *.java command , I dont get this out of memory error.
Then when I tried to use
<compilerarg
line="-J-mx1000000000"/>
but I am getting some
syntax errors like :
The <javac> task doesn't
support the nested
"compilerarg" element
Following is the part of the build xml file, which I am using.
<target name="compile" depends="init">
<echo>Compiling ${ant.project.name}</echo>
<echo>class path ${classpathref}</echo>
<property name="classpathref" value="${jar_classpath}"/>
<mkdir dir="${sap_jar_input}"/>
<javac srcdir="${javacc}"
destdir="${class_dest}"
/>
<echo>Finished compiling ${ant.project.name}</echo>
</target>
Would you please go through the above snippet & tell me how to use
<compilerarg line="-J-mx1000000000"/> ???
Please suggest some better way of doing this if there is any.
* I want to ask you one more question..
I need to build the java files once in a while.
Now , sometimes when the build fails, I have to take a lower version of
the failed file.
In that case if I am using javac -J-mx1000000000 -d $TEMP_SOURCE *.java
command from the unix prompt , I need to recompile
all the 1200 files.
How I can avoid this & compile only those previously failed files in the
second round & create the jar file ??
This will save a lot of time.
Thanks for your valuable time.
