Maven Dependency Plugin appendOutput Parameter is Failing? - maven

Question

UPDATE: This issue seems to have resolved itself. I could still produce it on a copy of the source code, but it was a temporary copy that I deleted before realizing I would need it to pin this issue down. I'm continuing to track this and see if I can identify a root cause. If not, I will close the issue.
When I run mvn dependency:list -DoutputFile=/path/to/file.txt -DappendOutput=true from the root directory of a multi-module Maven project, the resultant output file only contains the dependencies of the last module declared in the modules section of the root pom.xml file. Is there something different I need to do to get the output of each submodule to append to the output file?
Configuration:
Maven 3.0.3
maven-dependency-plugin 2.6

Answer 1

When I'm using the following command: -
mvn dependency:list -DoutputFile=/path/to/file.txt -DappendOutput=true
The result is invalid and the Maven told me that
[INFO] --- maven-dependency-plugin:2.1:list (default-cli) # ...
Then I change to specify the version
mvn org.apache.maven.plugins:maven-dependency-plugin:2.6:list -DoutputFile=/path/to/file.txt -DappendOutput=true
The result is valid and the Maven told me that
[INFO] --- maven-dependency-plugin:2.6:list (default-cli) # ...
I would suggest you to ensure that the executing is the version 2.6. Anyhow I always use the following command as
mvn dependency:list > /path/to/file.txt
IMHO the result is better and more clear for each module as the following example: -

I hope this may help.
