Hello, I'm Ondřej Žižka and I'll show you how to build Windup from the source code
  and run it against your application, getting an HTML report in the end.

  First, visit Windup project on GitHub.
  Copy the Git URL.
  Then clone the repository.

git clone git@github.com:windup/windup.git Windup

  This will take a while.
  ...
  For details about individual steps, visit Windup wiki and see the Build Windup from Source.
  ...

  Then, go to the freshly created project directory and build Windup using Maven 3.2.1 or later.
cd windup
mvn clean install -DskipTests
cd -

  Meanwhile, download and unzip the Forge project:

wget -O forge.zip https://repository.jboss.org/nexus/service/local/repositories/releases/content/org/jboss/forge/forge-distribution/2.10.1.Final/forge-distribution-2.10.1.Final-offline.zip
unzip forge.zip
mv forge-distribution-2.10.1.Final Forge

  Then make the Forge executables available from anywhere.

export FORGE_HOME=./Forge/
export PATH=$PATH:$FORGE_HOME/bin

rm -rf ~/.forge/addons

  Now Forge is ready for the installation of Windup addons.
  Check if the Windup build has finished...
  We will need the UI addon, and 2 rules addons with Java related rules.


forge -b --install org.jboss.windup:ui,2.0.0-SNAPSHOT
forge -b --install org.jboss.windup.rules.apps:rules-java,2.0.0-SNAPSHOT
forge -b --install org.jboss.windup.rules.apps:rules-java-ee,2.0.0-SNAPSHOT

  After installation, run Forge.
forge

  In the Forge environment, run the `windup-migrate-app` action. For information about the parameters, run
man windup-migrate-app

  Notice the --input and --output parameters, which are mandatory.
windup-migrate-app --input /home/ondra/work/Migration/TestApps/_apps/BradApp --output Report --sourceMode=true --packages org com net

  Give Windup few seconds, or minutes - depending on if you have an SSD disk or not.
  ...
  Then exit Forge by pressing Control-D.
Ctrl + D

  Check the resulting report by opening the HTML file.

firefox Report/reports/JEE_Example__org_windup_example_jee_example_1_0_0_.1.html

  For explanation of the report, see Windup wiki page called "Review the Report".

  Thanks for your attention.
