# tycho-transitive-demo

1. Build the `my.tycho` project, then the `my.maven` project.

    ```bash

    cd my.tycho

    mvn clean install

    cd ..

    cd my.maven

    mvn clean install

    ```

2. Try to run the `my.maven` project.

  ```bash

  java -jar target/my.maven-1.0.0-SNAPSHOT.jar 

  ```

  It will throw an error:

  ```

  Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/collect/ImmutableMap

    at my.tycho.TychoWorker.sayHello(TychoWorker.java:8)

    at my.maven.MavenMain.main(MavenMain.java:8)

  Caused by: java.lang.ClassNotFoundException: com.google.common.collect.ImmutableMap

    at java.net.URLClassLoader.findClass(URLClassLoader.java:381)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:424)

    at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:331)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

    ... 2 more

  ```

  

3. To fix this, you have to define the dependency explicitly. Edit the `pom.xml` file in the `my.maven` project by uncommenting the Guava dependency:

  ```xml

  

  

	com.google.guava

	guava

  	15.0

  

  ```

4. Run the build and the application again:

  ```bash

  mvn clean install

  java -jar target/my.maven-1.0.0-SNAPSHOT.jar 

  ```

  

  It will display the correct output:

  

  ```

  {hello=world}

  ```
