Cannot get HelloMaven example running

I am trying to use moe from Maven. I have found the Hello Maven example, but when I:

git clone
cd moe-samples-java/HelloMaven
mvn clean install

it fails with followng message:

dependencies could not be resolved: Could not find artifact org.multi-os-engine:moe-maven:jar:1.3.1 in central (

This error can be solved by adding plugin repository into the pom file:

--- a/ios/pom.xml
+++ b/ios/pom.xml
@@ -17,6 +17,13 @@
+    <pluginRepositories>
+        <pluginRepository>
+            <id>jcentral</id>
+            <url></url>
+        </pluginRepository>
+    </pluginRepositories>

with that fix the example gets further, but still fails when I try cd ios; mvn moe:launch -X the error is not really printed, this is the last few lines from the output:

[INFO] Injars: -Pmoe.proguard.injars=/prj/moe-samples-java/HelloMaven/ios/target/classes:/prj.m2/repository/org/multi-os-engine/common/1.0.0-SNAPSHOT/common-1.0.0-SNAPSHOT.jar

Any advice welcomed.


Please check your gradle moeGenerateUIObjectInterfaces task log file.
Log location is …/HelloMaven/ios/build/moe/main/ui-headers/GenerateUIHeaders.log

Best Regards,

If I execute:

$ find build/moe/ | grep log$ | xargs cat

I can see the failure. I have some problem with credentials - but why are the credentials needed at all? I only want to run in a simulator, I don’t have any real device attached…

Few suggestions from my experience:

  • can the sample pom.xml be enhanced to have the pluginRepository definition? (if that is the right way) Otherwise the maven approach doesn’t seem to work for me at all.
  • shouldn’t the Maven plugin print out the failed log file automatically? It is tedious to always seek for *.log files in build directory
  • shouldn’t the moe:launch command work without credentials if I have no iOS device attached?

Thanks for showing me where to find the log files and possibly considering some of my ideas.
