How to set up my eclipse project to build a jar file from two jar files [message #257372]

I use eclipse 3.4.1 on FC6 linux.
My java source layouts are as follows:
/home/twong/java/myjar/com/mycomp/cpt/
/home/twong/java/myjar/com/mycomp/cptx/
/home/twong/java/myProc/myProc
/home/twong/java/myProc/myProc.mf

My workspace is at:
/home/twong/eclipseworkspace

My build instructions are:
cd /home/twong/java/myjar
javac -classpath ibmpkcs.jar -d . /*.java com/mycomp/cptx/*.java
jar -cf myjar.jar com/mycomp/crypto/*.class
jar -cf myjarx.jar com/mycomp/cptx/*.class

myjar.jar and myjarx.jar are used to build myProc.jar.
cd /home/twong/java/myProc
javac -d . myProc/*.java
jar -cfm myProc.jar myProc.mf myProc/*.class

This is the command to run my application:
java -jar /home/twong/eclipseworkspace/myProc.jar

What is the best way to set up my project to build myProc.jar from
myjar.jar and myjarx.jar?

Do File → Export → Java → Runnable Jar file. If you want this to happen
automatically, look at the build file produced and adopt this into your
own Ant build file.

You'll have to write an small Ant script to do it and then incorporate
that script as a custom builder. See this for how to define a custom
builder:

Hope this helps,

Now I use custom build script to build a jar file on eclipse 3.4.1 & FC6.
It build the first time but fail to build with this message:
Note: myProc/myProc.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

The custom build script makejar.sh is as follows:
#!/bin/bash
javac -d . myProc/*.java
jar -cfm myProc.jar myProc.mf myProc/*.class

Running the custom build script as a shell script always build the jar
file even though a warning appear.
$ ./makejar.sh
Note: myProc/myProc.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.

Please help to make the custom build script always build inside eclipse.
Thanks.
