Creating your first Play 2.1 app



Follow the official install instructions (these steps will only work for 2.1.* versions of the Play Framework). Afterwards:

  1. play new myFirstApp creates a new app, in the current directory, inside a new folder called myFirstApp
  2. Now try to run it. First go inside that folder (cd myFirstApp), and run it (play).
  3. [Optional step] You can transform your Play application into an Eclipse project, by running play eclipse. If you want Play’s source files and javadoc to be attached to the Eclipse project, you should execute play "eclipse with-source=true" instead.

If during step 2 you get this error:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.

You can solve it if you:

  1. Edit %PLAY_HOME%\framework\build.bat script
  2. Remove the command line argument for the command below: java -Xms512M -Xmx1024M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M %DEBUG_PARAM% -Dfile.encoding=UTF8 -Dplay.version="%PLAY_VERSION%" -Dsbt.ivy.home="%~dp0..\repository" -Dplay.home="%~dp0.""file:///%p%sbt/" -jar "%~dp0sbt\sbt-launch.jar" %*
  3. Replace with java -XX:+CMSClassUnloadingEnabled %DEBUG_PARAM% -Dfile.encoding=UTF8 -Dplay.version="%PLAY_VERSION%" -Dsbt.ivy.home="%~dp0..\repository" -Dplay.home="%~dp0.""file:///%p%sbt/" -jar "%~dp0sbt\sbt-launch.jar" %*
