Re: Company-wide pom and dependency management best practices
I remember talking with Herve Boutemy at Devoxx FR and he told me about an upgrade of the help:effective-pom ( https://maven.apache.org/plugins/maven-help-plugin/effective-pom-mojo.html ) that would not only display the effective pom but also for each line the source pom where this value comes from. You can force the use of the latest help plugin with this line: mvn org.apache.maven.plugins:maven-help-plugin:3.2.0:effective-pom -Dverbose=true The verbose parameter is mandatory to have the origin info as comment for each line. Hope it helps ! *- - - - -François Marot* On Tue, 6 Aug 2019 at 16:50, Nick Stolwijk wrote: > Thanks Tomo, > > > I use "mvn dependency:tree -Dverbose=true" to get the detail of tree.

Re: Company-wide pom and dependency management best practices
Thanks Tomo, > I use "mvn dependency:tree -Dverbose=true" to get the detail of tree. It shows unselected nodes. The only problem with the verbose route is that it can show wrong results on Maven 3[1][2]. I was hoping for a non-deprecated solution.

Yeah, it seems that would be the best option.

Company-wide pom and dependency management best practices
Hi all, We have a company-wide pom for specific applications. In our case for Spring Boot applications. In this pom some of the stuff is for the build (plugin management, deployment management) and some for the dependencies (scope import for dependencyManagement). We had a buildproblem where one of the Spring Boot dependencies had the wrong version. It turned out the version of one of the dependencies for Spring Boot was overridden by another dependencyManagement import. The first question is, how can I see where the different versions for a dependency are coming from? I know of the dependency:tree, but that only shows the resolved version and not all the version options. The second question is, how can I make sure that the dependencies in the Spring Boot import take preference over the other dependency imports. My idea is to break apart the Spring Boot parent we have into a build pom and a dependency management pom and require that every application import the dependency import pom as first dependency under dependency management. Would this work or am I missing something? Is there any documentation about the best practices for inheriting build configuration and dependency management? With regards, Nick Stolwijk ~~~ Try to leave this world a little better than you found it and, when your turn comes to die, you can die happy in feeling that at any rate you have not wasted your time but have done your best ~~~ Lord Baden-Powell
