jenkis 部署eclipse 项目时使用ant打包，处理ant打包出错

获取ant 打包的返回的code，然后根据code来处理逻辑

cd $PROJECT_PATH/ && ant -buildfile jenkins_build.xml war
antReturnCode=$?
echo "ANT: Return code is: ""$antReturnCode"""
if [ $antReturnCode -ne 0 ];then
    echo "ant deploy failed!"
    exit 1;
else
    echo "ant deploy success！"
fi
