Hi suho, Thanl you for the information. In the initial build i used mvn "mvn clean install -Dmaven.test.skip=true", thats why i did not get errors.But this time i built with mvn clean build and i got some errors in test stage.i have already set up MAVEN_OPTS as MAVEN_OPTS="-Xms768m -Xms3072m -XX:MaxPermSize=1200m". But it seems to be some memory constriant.i got followings.
ERROR [org.wso2.carbon.automation.extensions.servers.utils.ServerLogReader] - Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0 ERROR [org.wso2.carbon.automation.extensions.servers.utils.ServerLogReader] - Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000000f4000000, 157286400, 0) failed; error='Cannot allocate memory' (errno=12) I have been using Ubuntu 14.04 LTS with 4GB ram.So how can i fix this issue. And i got similar kind of error when i was trying to build the wso2 product-ml. i have attached the detailes of the error i got in this mail. Do i need to set up some additional environemtn variables to fix this. BR, Mahesh.
