What is ${session.executionRootDirectory} and how to set it

Question

I am using dl4j examples in my system. It's a maven project with various modules. There are several pom files in it. In the parent pom file I noticed I got an error stating:

Cannot resolve symbol 'session.executionRootDirectory'

.

I don't remember changing this line (or this pom file either). The line producing the problem is this one:

<configFile>${session.executionRootDirectory}/contrib/formatter.xml</configFile>

in file parent pom file line 90.

My question is since ${session.executionRootDirectory} seems as a variable which my system fails to identify is it something of an environment variable I should set? Should this be set by another way? Any idea of what ${session.executionRootDirectory} is and how to set it welcome.

My system is win7 and I am using Intellij Idea.

The problem seem to be solved by replacing the variable with an actual value of the path to the file it points to (that is formatter.xml) but I would like to know why the solution with the variable does not work.

It's a maven property check : https://maven.apache.org/examples/injecting-properties-via-settings.html — alain.janinm, Oct 13 '17 at 09:25
In the maven instruction it refers to a Settings.xml file. Where is supposed that file to be? — Eypros, Oct 13 '17 at 09:56
I think in .m2/settings.xml. You can also set a specific path, see documentation : https://maven.apache.org/settings.html — alain.janinm, Oct 13 '17 at 11:58
alain don't you want to write an answer so I can choose it as solution? — Eypros, Oct 16 '17 at 06:34
Sure, feel free to edit it to add details if needed. Thanks! — alain.janinm, Oct 18 '17 at 15:00
I do not think that session.executionRootDirectory is a configuration in settings.xml. session is a root object that has the method getExecutionRootDirectory().

Values between ${...} are Maven property. You can read the documentation for a detailed explanation here.

Values have to be be configured in a settings.xml file.

This file may live in:

The Maven install: ${maven.home}/conf/settings.xml
A user’s install: ${user.home}/.m2/settings.xml

For more details about settings.xml, check the Maven documentation.

No it is in your project path:

dl4j-examples/contrib/formatter.xml
