It looks weird, but intuition tells me it is not maven problem but config

We haved dived into that more and it is not a config issue...I can 
reproduce the problem...(We have not yet the root cause)...


But you can see the description here:

Yes however the compiler-plugin (or the tools API) may fail to detect failed 
forks/exec, which would also be a thing for Maven to improve.

2017-08-09 Thread Karl Heinz Marbaise 

Hi,

can you give a full working example of that...

cause it sounds like there is something wrong with your configuration...

What does: "mvn --version" says?

Are you trying to run in console or running from inside of Eclipse?

Kind regards

Re: How is the best way to get an effective POM outside of a Maven Plugin?

2017-08-09 Thread Karl Heinz Marbaise 

Hi Sandra,

first question: Do you need the full resolved pom (effective pom) or 
would it be enough just to simply to parse the pom file which can simply 
being done using MavenXpp3Reader this would deliver the XML as a Maven 
Model class which can simply being used to extract information from the 
maven model...


Kind regards

How is the best way to get an effective POM outside of a Maven Plugin?
