Bamboo build time

[techops]

Hey everybody, any hints on how we can reduce the build time? we are running a java application in bamboo and the build already takes > 40minutes.. this is insane for testing.. any tips what we can look at?

Are you using the same Maven version on both local machine and Bamboo?

1. Try to use MAVEN_OPTS to increase allocated memory for the maven jvm process.

Bamboo Maven task > Envrionment Variables :
Something like: MAVEN_OPTS="-Xmx1024m -XX:MaxPermSize=256m"

2. Maven 3.x has the capability to perform parallel builds:
mvn -T 4 clean install #run your build with 4 threads
mvn -T 2C clean install #build your project with 2 threads per core

Have a look at https://cwiki.apache.org/confluence/display/MAVEN/Parallel+builds+in+Maven+3

Hi,

what kind of java build tool are you using? Maven? Gradle? Are there any tests performed?

[techops]

Hey yes we use MAVEN and we run tests. The whole build process on our local machines (which are not particualry strong) takes about 5-7 minutes. on bamboo it takes > 30 minutes.
