I wrote a shell script that runs on remote host to build source code with 'ant build' command, and then distribute the built binary to other servers.

However, right after Ant build is over successfully(I can see the command line output saying Build was successful), the ssh session ends and whatever commands after 'ant build' does not get executed.

I'm confused what might be cause of this behavior. I suspected that it might be because the 'ant build' command takes too long time, and SSH somehow quits itself after that long command. But I don't think that's correct since if I just do 'sleep 60' in place of 'ant build' command, it actually execute latter commands as intended.

I'm new at shell programming, so I might have made some silly misassumption. Can someone provide a pointer to a possible cause of this problem?

My shell script

#!/bin/bash
# Inject some variables

ssh -T $SSH_USER@$SSH_URL "setenv REMOTE_BASE_DIR $REMOTE_BASE_DIR; setenv CASSANDRA_SRC_TAR_FILE $CASSANDRA_SRC_TAR_FILE; setenv CASSANDRA_SRC_DIR_NAME $CASSANDRA_SRC_DIR_NAME; setenv CLUSTER_SIZE $CLUSTER_SIZE; setenv REMOTE_REDEPLOY_SCRIPT $REMOTE_REDEPLOY_SCRIPT; /bin/bash" << 'EOF'

export JAVA_HOME=/usr/lib/jvm/jdk1.7.0

cd $REMOTE_BASE_DIR/$CASSANDRA_SRC_DIR_NAME

echo "## Building Cassandra source"
ant clean build

# Anything after this doesn't run
echo "## Ant Build is over. Invoking redeploy script on remote nodes"

# Invoke redeploy script for each node
for (( i=0; i < CLUSTER_SIZE; i++))
do
echo "## Invoking redeploy script on node-$i"

done

Command-line output
