Getting Started

To begin, ensure that you have the prerequisite software installed as enumerated below. You will
need internet access to pull down the project dependencies from a public Maven repository.

Use git to clone the repository

Prerequisites

You will need an internet connection (at least for the first build) for the dependencies to be downloaded into your local maven repository.
To build this repository, you will need the following installed on your machine:

  • git 2.14+
  • Java 8 JDK
  • Maven 3.0+


Note that Plastic has not been ported yet past Java 8

Building From Code

Pulling The Code

For read-only access, you can do this

git clone https://git.opendaylight.org/gerrit/plastic

For a committer, you can do this

git clone ssh://{username}@git.opendaylight.org:29418/plastic.git

Building

Once you have the prerequisites and have cloned the repo, you can issue a build at the
top level of your local copy of the repo

cd plastic
mvn clean install

The build should complete normally. You can look in the target directory for artifacts.
There should be a plastic-*.jar and a directory called runner. If you change your current
working directory to the runner directory, you can issue the following command to see
things work (this uses examples from the tutorial)

./plastic_runner runnerroot.properties

You should see log output that shows a successful translation from "abcd" to "ABCD".

Running the tests

Most of the testing is done using unit tests that are written using Spock (a highly recommended
alternative to JUnit). These tests are run as part of every single build and a failure of
a unit test breaks the build.

Using a Plastic distribution

Plastic is 100% independent of ODL code/dependencies and can be used stand-alone. Plastic is available several places including Maven Central and you can insert the dependency in your POM like the below example.

<dependency>
    <groupId>org.opendaylight.plastic</groupId>
    <artifactId>odl-plastic</artifactId>
    <version>2.1.7</version>
</dependency>

Once you have the depedency, create an arbitrarily named folder, lets call it my-plastic, with the following required structure. Note that the directories can be empty but they are required.

my-plastic/
    lib/
    morphers/
    schemas/
    classifiers/

To use the Plastic logic, you can create a new SearchPath("/opt/myapp/my-plastic") instance, passing the file system location to that root directory, and pass that to a new instance of CartorapherWorker. This worker's lifetime should be that of your application. Just call worker.translate(...) for each translation.

Out-of-the-box tutorial examples

There is a set of tutorials in the target/runner directory. You can find them as *.RST files. You
can install rst2pdf and convert them to PDF if you'd like.

From the target/runner directory, you can execute any of the tutorial examples
using a command like

./runner <name>.properties
