This implementation is compatible with pcf's Interceptable interface (https://github.com/douglas444/pcf).

• Apache Maven 3.6.3 or higher
• Java 8

• streams 1.0-SNAPSHOT (https://github.com/douglas444/streams)
• pcf-core 1.0-SNAPSHOT (https://github.com/douglas444/pcf)
• JUnit Jupiter API 5.6.2 (available at Maven Central Repository)
• Apache Commons Math 3.6.1 (available at Maven Central Repository)

First you need to install echo at your Maven Local Repository. This can be done by executing the following command line from the root folder:

mvn clean install

Once you have installed echo, import it at your Maven project by including the following dependency to your project's pom.xml file (edit the version if necessary):

<dependency>
  <groupId>br.com.douglas444</groupId>
  <artifactId>echo</artifactId>
  <version>1.0-SNAPSHOT</version>
</dependency>

For an example of how to use echo in your code, check out the file src/test/java/br/com/douglas444/echo/ECHOTest.java.

First of all you need to build the project's JAR. This can be done by executing the following command line from the root folder:

mvn clean package

If you want to build the JAR with the dependencies included, execute the following command line instead:

mvn clean package assembly:single

Once the process is finished, the JAR will be available at the target folder as echo.jar or echo-jar-with-dependencies.jar.

Once you have the JAR, load it in the classpath section of the pcf-gui. After that, the class ECHOInterceptable should be listed in the graphical interface.

• We configured the JAR's build process in a way that, even if you choose to build with the dependencies included, the pcf-core dependency will not be included. The reason is that the pcf-core dependency is already provided by the pcf-gui when the JAR is loaded through the graphical interface.

• If you choose to build the project without the dependencies included, make sure to load all the dependencies' JAR individually at the pcf-gui graphical interface. There is no need to load the pcf-core dependency though, since it is already provided by the pcf-gui.
