How to gather copyright notices using Maven License Plugin?

Question

I use many open-source libraries in my project and I use license-maven-plugin to gather information about them. I can see all the license texts in the target directory and THIRD-PARTY-included-modules.txt as follows:

Lists of 144 third-party dependencies.
 (Apache License 2.0) Commons Codec (commons-codec:commons-codec:1.8 - http://commons.apache.org/proper/commons-codec/)
 (Apache License 2.0) Commons IO (commons-io:commons-io:1.4 - http://commons.apache.org/io/)
 (Apache License 2.0) Commons Logging (commons-logging:commons-logging:1.1.3 - http://commons.apache.org/proper/commons-logging/)
 (CDDL) JavaBeans Activation Framework (JAF) (javax.activation:activation:1.0.2 - http://java.sun.com/products/javabeans/jaf/index.jsp)
...(and 140 more lines)

However, this doesn't seem to match the legal obligations:

(from MIT license) The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

As far as I can read, I'm supposed to include notices such as:

Copyright (C) 2011, 2014, 2015 Tatsuhiro Tsujikawa

How am I supposed to gather the copyright notices that I should include in the About page?

Here is my pom.xml:

                    <!-- Same as 'missingFile' but in XML, probably -->
                    <licensesConfigFile>src/license/licenses-manual.xml</licensesConfigFile>

                    <!-- Output folder -->

                    <!-- Text with the output list of all licenses. Just contains the list of projects and websites, does not contain the copyright notices -->

                    <!-- XML with the output list of all licenses -->

                    <!-- Folder with an output dump of all license text. Usually they contain the license template (for APL2) but not the copyright notices. -->
                    <licensesOutputDirectory>target/classes/META-INF/licenses/text</licensesOutputDirectory>

                </configuration>
            </plugin>

How am I supposed to gather the copyright notices with the license-maven-plugin (or any other tool)?

我不知道有任何有效的版权扫描器/收集器可用作 Maven 插件。但是您可以使用 ScanCode 工具包来收集版权：它就是为此目的和其他相关目的而设计的。（免责声明：我是那里的开发人员之一）

这仅需要 Python 2.7 解释器，安装后运行 ./scancode -c 即可获取 JSON 格式的版权。

将扫描代码包装在 Maven 插件中应该相当容易。把招工广告！
