Ant on Linux
Hi all,
I have been trying with not much success to get Ant up and running on Linux
(Mandrake 7.2). Is there any special differences between Windows and Linux
that I should be aware of? I have been running Ant quite successfully on NT
for a while now. I have a requirement to set up a Linux build environment
and hence the problem.
Thanks in advance,
Dan MacKay

One possibility is that you are using kaffe compiler/interpreter instead of
sun/ibm/whatevers version. To make sure you are not try java -version or
looking in RPM DB to see if you have kaffe installed. If it is installed
then remove it and try again ;)
Cheers,

Hi Dan,
IMHO, the ant batch and shell scripts have a bug in them. You can set
JAVA_HOME and instead of the ant script running $JAVA_HOME/bin/java as you
would expect, it happily runs whatever java executable it finds first in
the PATH which might not be the one you expect.
In your .bashrc after setting JAVA_HOME try adding:
export JAVACMD=$JAVA_HOME/bin/java
The ant script will now run whatever java executable is exported as
JAVACMD and will not run whatever java executable it finds first in the
PATH.

What does java -version give you? Unfortunately the shell script will
use the version of java from your PATH, not the one in JAVA_HOME. I
suspect you are running kaffee instead of the jdk1.3 you intend to
run.

Hi Weigi,
Here is what I have done and the setup I have:
I logged in as root and installed
ant in /usr/local/bin/ant from the latest jakarta-ant-bin.tar.gz
jaxp in /usr/local/jaxp1.0.1
This is the .bash_profile:
PATH=$PATH:$HOME/jtest/bin:$HOME/bin:/usr/local/jdk1.3
BASH_ENV=$home/.bashrc
USERNAME=""
ANT_HOME=/usr/local/bin/ant
JAVA_HOME=/usr/local/jdk1.3
XML_HOME=/usr/local/jaxp1.0.1
CLASSPATH=$CLASSPATH:/usr/local/bin/junit3/junit.jar:$XML_HOME/jaxp.jar:$XML
_HOME/parser.jar
and then I export all the variables
When I attempt to run ant I consistently get the following error:
Couldn't find or load essential class 'java/lang/object'
java.lan.NoClassDefFoundError java/lang/object
usr/local/bin/ant/bin: line 1411 aborted
Any ideas would be appreciated.
Thanks,
Dan

I run Ant on Linux all the time. What kind of problems are you running
into?

Apart from running bootstrap.sh instead of bootstrap.bat 8-)? No.
I have JAVA_HOME set to the root of my JDK and the bootstrap script
simply works out of the box (RedHat 6.2, regularily switching between
Blackdown's 1.1.8, IBM's and Sun's 1.3 and Blackdown's 1.2.2).
Could you post the error messages bootstrap.sh generates?

Dan,
Not much to go on there. Can you give us more info? Could be a
line-ending problem if you moved stuff from your NT system directly but
I am only guessing.

Hi all,
I have been trying with not much success to get Ant up and running on
Linux (Mandrake 7.2). Is there any special differences between Windows
and Linux that I should be aware of? I have been running Ant quite
successfully on NT for a while now. I have a requirement to set up a
Linux build environment and hence the problem.
Thanks in advance,
