Re: Strange dataBase error
If you haven't "locked down" your dependency versions, it is possible that someone has "polluted" their local repo cache with SNAPSHOT versions of some of them, etc. It is not absolutely true that every build across a group of machines will necessarily produce the exact same artifact. Also it is very easy to introduce build differences through profile activation etc. So don't assume anything without verifying it.

Re: Strange dataBase error
Thanks for the answer, I will take a look at this issue. On every machine I build jars using command mvn install (I have multi-level project and few jars are created) Wayne Fay wrote: > > If the Jars and code etc is the same, there must be an environmental > difference between the machines where the tests pass and where the > tests fail. > > Are you building the Jar(s) repeatedly (on different machines) or just > building once and then re-using that built code in your various tests? > If you're not re-using the same Jar, then you really can't be sure > about anything.

Re: Strange dataBase error
If the Jars and code etc is the same, there must be an environmental difference between the machines where the tests pass and where the tests fail. Are you building the Jar(s) repeatedly (on different machines) or just building once and then re-using that built code in your various tests? If you're not re-using the same Jar, then you really can't be sure about anything. So build it once and then use that for testing. Also, perhaps you should unzip a Jar that works and a Jar that doesn't work, and run a diff/compare tool against the 2 directories. There might be some differences that you weren't expecting.
