Can you try running it again with the `-X` parameter, e.g. `mvn -X clean install`. ---

logs are kinder big,i had to use note pad.On running `mvn -X clean install` i get [logs.txt](https://talk.openmrs.org/uploads/short-url/3PO7oKKdpk16sCy0kCNRZfiHSYQ.txt) (760.6 KB) ---

In [theory](https://maven.apache.org/surefire/maven-failsafe-plugin/faq.html#corruptedstream) that should’ve given us some more information, but I’m none the wiser for having looked at that. Do things work if you run `mvn clean install -Dfork=false`? ---

Ok… two suggestions: 1. Can you pull the latest changes to Core? @dkayiwa just updated the Jacoco version in core and I suspect that’s the part that’s causing the issue. If that doesn’t work try: 1. Comment out [this plugin](https://github.com/openmrs/openmrs-core/blob/95b784175f73ad767242ff9d1ec83ad1be99e6c2/pom.xml#L789) in your local copy of the POM, but please don’t commit that. PS I’m sorry I don’t have an easy solution for you. ---

@ibacher to solve this i have specified the maximum allowed JVM heap size ie added this to the environment variables in windows,Variable name: \_JAVA\_OPTIONS and Variable value: -Xmx512M.I can now run mvn clean install successfully thanks much ---

@herbert24 can you confirm that we you change that to a lower value, you get exactly the same error as before? ---
