How can I get only root module's dependencies when use -outputDirectory

I use this project https://github.com/mokarakaya/spring-boot-multi-module-maven.

If I run command mvn com.github.ferstl:depgraph-maven-plugin:graph -DgraphFormat=text -DshowDuplicates -DshowConflicts -DshowVersions -DshowGroupIds in path spring-boot-multi-module-maven/, I will get three target folder in spring-boot-multi-module-maven/, spring-boot-multi-module-maven/api/ and spring-boot-multi-module-maven/web/ separately. And the spring-boot-multi-module-maven/target/dependency-graph.txt shows:

webDemo:webDemo:1.0-SNAPSHOT:compile

But if I run command mvn com.github.ferstl:depgraph-maven-plugin:graph -DgraphFormat=text -DshowDuplicates -DshowConflicts -DshowVersions -DshowGroupIds -DoutputDirectory="spring-boot-multi-module-maven/", in path spring-boot-multi-module-maven/. The dependency-graph.txt shows all dependencies of modules but not webdemo only.

how can I get

webDemo:webDemo:1.0-SNAPSHOT:compile

when use -outputDirectory at the same time?

Thanks!

What happens here (when you use an absolute path) is, that each module will write its dependency graph into the same directory under the same name. So what you see is the dependency graph of the last module in the Maven reactor since the others were overwritten. To avoid that you can add -DuseArtifactIdInFileName=true when using absolute paths. This will produce different file names and you will see all three dependency graphs in that directory.

Another question. What if I only want to get the dependency graph of the parent module, webdemo here, and skip the other modules api and web? That is, only one file in that directory.

You can try the following:

• Run Maven with the -N (non-recursive) option. This will only build the parent module without the sub-modules.
• Use a <plugin> configuration with <inherited>false</inherited> as described here: https://maven.apache.org/guides/mini/guide-configuring-plugins.html#Using_the_inherited_Tag_In_Build_Plugins
