How to Build XLT

The XLT build process is based on the Apache Ant build tool. The build works best when being run on a Linux machine.

Required Tools

• Latest JDK 8 (or 11)
• Latest Apache Ant
• Chrome or Chromium browser (to package the timer-recorder extension for Chrome/Chromium)
• Optional tools:
  • Only if you want to run the XLT unit tests:
    • chromedriver
    • geckodriver
  • Only if you want to build the XLT documentation:
    • Jekyll

Building XLT

To create the XLT distribution archive xlt-X.Y.Z.zip, run the following command. If all went well, the archive can then be found in folder target/dist.

ant clean dist

If you want the HTML documentation (manual, release notes, how-to) to be included in the distribution archive, run this command:

ant clean dist -Dcreate.doc=true

To perform a release build which requires all unit tests to pass, run any of these commands:

ant clean release 
ant clean release -Dcreate.doc=true

Limitations

When you build XLT by yourself, the following limitations apply.

• The timer-recorder extension for Firefox is not signed yet. Hence, when using XltFirefoxDriver later on, Firefox will refuse to install that extension. If you need the extension, download the official XLT distribution which contains a correctly signed extension.

Building on Windows or macOS

• Some unit tests are known to fail on Windows.
• You will need to adjust the path to Chrome/Chromium in build.properties according to your system.
