Maven, relative path to local directory

Question

I want to copy files in ".jenkins" or in "Temp" direcotry.

<artifactId>maven-resources-plugin</artifactId>
    <version>2.7</version>
    <executions>        
      <execution>
        <id>copy-resource-one</id>
        <phase>install</phase>
        <goals>
          <goal>copy-resources</goal>
        </goals>
        <configuration>
          <outputDirectory>C:\Users\user\.jenkins</outputDirectory>
                    <resources>
                        <resource>
                            <directory>${basedir}/src/main/resources</directory>
                            <includes>
                                <include>htmlTemplate.html</include>
                                <include>Chart.js</include>
                            </includes>
                        </resource>
                    </resources>
          </configuration>                        
      </execution>
    </executions>

This is how my pom.xml looks like for now. It is working for me on my local machine, but it won't work for another user.

This is what I want:

<outputDirectory> relative path to Temp </outPutDirectory>

Question: How can I ensure that the file is always copied in "temp" or in ".jenkins" folder? Is there any variable for that?

Answer 1

In Maven you can use Java properties as Maven properties for a build.

Maven exposes all properties from java.lang.System. Anything you can retrieve from System.getProperty() you can reference in a Maven property

So, in your case you could have the following:

<outputDirectory>${java.io.tmpdir}</outputDirectory>

And the output directory will point to the user temporary directory based on the host OS. For instance, in Windows 7 it would be

C:\Users\<user_Id>\AppData\Local\Temp

For a full list of Java properties, check official documentation, from which:

java.io.tmpdir: Default temp file path

You may also be interested in the user.home

user.home: User's home directory

So you probably wanted to point to ${user.home}\.jenkins.
