Java file is not getting compiled in cron

I run a script file through CRON daily which involves running selenium testcases and sending the report as mail. Here is my script: check.sh

#!/bin/sh
set -x
./.bashrc
export CLASSPATH=/home/test/TestAutomation/lib/*:.
cd /home/test/TestAutomation/lib/
/usr/bin/java -jar selenium-server.jar & 
cd
javac Api.java
java Api 
cd /home/test/TestAutomation/selenium/reports/
cp result.html /home/test/TestReports
sh /home/test/repgen.sh
sleep 30
sh /home/test/masRepgen.sh

This script works fine in cron. In this, sh /home/test/masRepgen.sh this script compiles and executes java file and Send Mail. I made a small change to the above script as follows.

#!/bin/sh
set -x
./.bashrc
. /home/test/blog/build.txt
cd /home/test/VT/CT/
if  [ -e /home/test/VT/CT/CT__$BuildLabel ]; then
echo "Testcases has been run already"
else
export CLASSPATH=/home/test/TestAutomation/lib/*:.
cd /home/test/TestAutomation/lib/
/usr/bin/java -jar selenium-server.jar & 
cd
javac Api.java
java Api 
cd /home/test/TestAutomation/selenium/reports/
cp result.html /home/test/TestReports
sh /home/test/repgen.sh
sleep 30
fi
sh /home/test/masRepgen.sh

After this change, I'm not receiving mail. ie., sh /home/test/masRepgen.sh doesn't compiling java class. I couldn't identify where the error is.

masRepgen.sh contains this.

cd /home/test/
/home/test/jdk1.7.0_12/bin/javac SendMail.java
/home/test/jdk1.7.0_12/bin/java SendMail "http://172.20.8.50/Regression/CR__$BuildLabel/compareresults_index.html" "http://172.20.8.50/Summary__$BuildLabel/complete_summary.html"

I added this in crontab:

45 02 * * * /bin/sh check.sh >> UI.txt
