Build step 'Deploy war/ear to a container' marked build as failure
To solve it I remove ROOT folder inside webapp directory and restart Tomcat , after that Deploy works fine , but only while ROOT folder doesn't exist. I think Jenkins can't redeploy the same application , what is the reason ?
Almas Abdrazak :
Finally I find an answer
In post build actions change
1)WAR/EAR files - > **/*.war instead of target/name.war
2)Context path - > / instead of ROOT
Don't forget to create manager gui (in my case it was configured but I found a lot of questions at stack where people didn't configure manager gui)
