    Details

      Description

      Here is a clue to reproduce the NPE.

                  <plugin>
                      <artifactId>maven-antrun-plugin</artifactId>
                      <executions>
                          <execution>
                              <phase>package</phase>
                              <configuration>
                                  <tasks>
                                      <unzip
                                          src="${project.build.directory}/${project.build.finalName}.${project.packaging}"
                                          dest="${project.build.directory}/xxx" />
                                  </tasks>
                              </configuration>
                              <goals>
                                  <goal>run</goal>
                              </goals>
                          </execution>
                      </executions>
                  </plugin>
      

      project.build.finalName is the previous value, and the interpolated value is null.
