在我的循环中运行ant会导致循环在一次传递后退出

Question

我的最后一个问题取得了如此成功,我决定再试一次.下面的bash循环设置为遍历文件并一遍又一遍地向ant发送消息,直到它遍历文件末尾.当我更改运行ant的命令以简单地回显命令(用于测试)时,它运行正常.当我删除"echo"和命令周围的引号时,它只运行一次脚本并优雅地退出循环.对我来说这似乎很明显,这与ant和退出状态有关,但我不明白为什么会让它退出循环而不是返回.顺便说一句,它总是返回零.

echo "Looping through database results and sending to ant..."
# This while loop runs through pendingtxs.result and funnels them to ant
while IFS=, read txid courseid instructorid
do
    echo "Beginning substitution of $1 into file..."
    sed -e "s/XXXXXXXXXX/$txid/" -e "s/YYYYYYYYYY/$courseid/" -e "s/ZZZZZZZZZZ/$instructorid/" createcourse_notif.template.xml >temp.xml
    echo "Substitution complete."
    echo "Sending the temp.xml to ant..."
    /xncpkgs/ant/bin/ant sendMessage -Dsend.destination=SmsQueue -Dmessage.file=temp.xml
    antReturnCode=$?
    echo "ANT: Return code is: \""$antReturnCode"\""
    echo "Ant is done"
    echo "Adding the xml to log.txt for later analysis"
    cat temp.xml >> log.txt
    echo "Removing temp.xml"
    rm temp.xml
    echo "Submission of $txid complete."

done < pendingtxs.result
