Hi, I am trying to get the Dhis2 development environment setup, but having problem making a successful project build using Maven. Could someone give me some help on this? I am not suppose to do this on Windows 7 64bit? I am using Windows 7 OS 64bit, Bazaar 2.5.1-1, JDK 1.7.0\_09, apache-maven-2.2.1 Followed ‘[http://dhis2.org/development](http://dhis2.org/development)’ ‘Quick start’ to download Dhis2 source code via ‘bzr branch lp:dhis2’ without doing the login via ‘bzr lp-login ’. However, when doing the ‘mvn install’ on ‘/dhis-2’, it keeps on giving me an error on datamart test part. > **···** > > ================================== > > Running org.hisp.dhis.datamart.DataMartServiceOrgUnitTestTests run: 5, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 3.437 sec \<\<\< FA > > ILURE! > > Results : > > Failed tests: testIndicatorDataMart(org.hisp.dhis.datamart.DataMartServiceOrgU > > nitTest): expected:\<482.6\> but was:\<480.6\> > > Tests run: 26, Failures: 1, Errors: 0, Skipped: 7 > > [INFO] ------------------------------------------------------------------------ > > [ERROR] BUILD FAILURE > > [INFO] ------------------------------------------------------------------------ > > [INFO] There are test failures. > > ================================== > > It doesn’t require database setup before doing this, does it? > > I have also tried downloading Dhis 2.9, and tried with JDK 1.6 and tried with apache-maven-3.0.4-bin. > > On those tries, I got a bit different DataMart related error and once on DHIS System Support build compile error. > > ================================== > > [ERROR] COMPILATION ERROR : > > [INFO] ------------------------------------------------------------- > > [ERROR] \DHIS2\2.9\dhis-2\dhis-support\dhis-support-system\src\main\java\org\his > > p\dhis\system\util\ReflectionUtils.java:[254,31] type parameters of T cannot > > be determined; no unique maximal instance exists for type variable T with upper > > bounds T,java.lang.Object > > ================================== > > Does someone know the exact version of JDK, Dhis, Maven, Bazaar that would work on Windows 7 64bit? ---

Hi James, I have had the exact same error on 64 bit Win7, with different JDKs. Only solution (not ideal) is to skip the tests. Look at the build.sh script. #!/bin/sh # Requires maven to be on the classpath # Skips test phase mvn clean install -DskipTests=true mvn clean install -DskipTests=true -f dhis-web/pom.xm Best regards, Jason > **···** > > On Sat, Oct 27, 2012 at 3:09 PM, James Chang \ wrote: > > > Hi, > > > > I am trying to get the Dhis2 development environment setup, but having > > problem making a successful project build using Maven. > > Could someone give me some help on this? > > I am not suppose to do this on Windows 7 64bit? > > > > I am using Windows 7 OS 64bit, Bazaar 2.5.1-1, JDK 1.7.0\_09, > > apache-maven-2.2.1 > > > > Followed '[Developer Resources - DHIS2](http://dhis2.org/development'); 'Quick start' to download Dhis2 > > source code via 'bzr branch lp:dhis2' without doing the login via 'bzr > > lp-login \'. > > > > However, when doing the 'mvn install' on '/dhis-2', it keeps on giving me an > > error on datamart test part. > > > > ================================== > > Running org.hisp.dhis.datamart.DataMartServiceOrgUnitTestTests run: 5, > > Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 3.437 sec \<\<\< FA > > ILURE! > > Results : > > > > Failed tests: > > testIndicatorDataMart(org.hisp.dhis.datamart.DataMartServiceOrgU > > nitTest): expected:\<482.6\> but was:\<480.6\> > > > > Tests run: 26, Failures: 1, Errors: 0, Skipped: 7 > > > > # [INFO] ------------------------------------------------------------------------ [ERROR] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] There are test failures. > > > > It doesn't require database setup before doing this, does it? > > > > I have also tried downloading Dhis 2.9, and tried with JDK 1.6 and tried > > with apache-maven-3.0.4-bin. > > On those tries, I got a bit different DataMart related error and once on > > DHIS System Support build compile error. > > > > # ================================== [ERROR] COMPILATION ERROR : [INFO] ------------------------------------------------------------- [ERROR] \DHIS2\2.9\dhis-2\dhis-support\dhis-support-system\src\main\java\org\his p\dhis\system\util\ReflectionUtils.java:[254,31] type parameters of \T cannot be determined; no unique maximal instance exists for type variable T with upper bounds T,java.lang.Object > > > > Does someone know the exact version of JDK, Dhis, Maven, Bazaar that would > > work on Windows 7 64bit? > > > > \_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_ > > Mailing list: [DHIS 2 developers in Launchpad](https://launchpad.net/~dhis2-devs) > > Post to : dhis2-devs@lists.launchpad.net > > Unsubscribe : [DHIS 2 developers in Launchpad](https://launchpad.net/~dhis2-devs) > > More help : [ListHelp - Launchpad Help](https://help.launchpad.net/ListHelp) ---

Thanks a lot, Jason. Running with ‘mvn clean install -DskipTests=true’ worked. I really appreciate your help.

Hi James, I have seen this before - data mart tests is failing in certain circumstances/JVMs. The funny thing is that they pass in most environments and I am not able to reproduce it. We need to closer on this.
