[milo-dev] Milo setup problems

[<Patrick.Pschorn@xxxxxxxxxxxxxxxxxx>]

Dear Milo community,

 

I am trying to set up Milo in Eclipse. I have checked it out over “Import …” -> Maven/Check out Maven Projects from SCM.

However, I am facing the following difficulties:

1)      In the “bsd-parser-core” and “bsd-parser-gson” projects, the imports in the under org.opcfoundation cannot be resolved. In the pom.xml of “bsd-parser-core” there is a maven error at line 53 “null (org.codehaus.mojo:jaxb2-maven-plugin:2.2:xjc:xjc:generate-sources)” which suggests a problem with the JAXB2 Maven Plugin (stack trace below)

2)      When running milo > maven clean and then maven install, the Test milo\opc-ua-stack\stack-core\src\test\java\org\eclipse\milo\opcua\stack\core\types\BuiltinDataTypeDictionaryInitializerTest.java throws an AssertionError “java.lang.AssertionError: null at org.eclipse.milo.opcua.stack.core.types.BuiltinDataTypeDictionaryInitializerTest.testInitialize(BuiltinDataTypeDictionaryInitializerTest.java:37)”
I have fixed this (very dirty) by just uncommenting line 37 //assertNotEquals(structures.size(), 0); which worked like a charm. The maven install ran successfully but there is no run configuration that I could use to start the Hello World example.

I have now tried a fresh import from existing Maven project (after downloading it again via git), and ran milo > maven clean and maven install. The Second issue has been resolved, there is no AssertionError anymore. However, I do not get any run configuration nor does it work to execute one of the projects as Java Application.

 

Some specs:

-          My eclipse version is  Oxygen.3 Release (4.7.3RC2)

-          java version "1.8.0_152"

 

The first issue seems to be similar to @samber86’s question in #226, however, he has been referred to the mailing list.

 

I would appreciate any help on this topic. Thank you in advance!

 

Best regards,

Patrick Pschorn
