\"let's-play-2\"<\/a><\/p>\n

Let’s assume you have an existing app using Play! 2.1.A<\/strong> and a 2.1.B<\/strong> version was released. You want to update your environment to use that new release. Note: This tutorial was tested to be working with 2.1.* versions; A and B are two arbitrary numbers.<\/p>\n

<\/p>\n

Updating environment<\/h2>\n

Like when installing a new version of Play:<\/p>\n

    \n
  1. Extract the Play 2.1.B<\/code> install package (zip) to %PLAY_HOME%\\play-2.1.b<\/code>. Attention: you must have read and write permissions on that folder.<\/li>\n
  2. Open a command line, go to the parent folder of %PLAY_HOME%<\/code>, open play-2.1.b<\/code> folder, type play<\/code> and enter. That will start the Play! installer. Wait for the installation to finish.<\/li>\n
  3. To finish up, you must tell your system to use the new Play version. To do so you must go edit your environment variable “%PLAY_HOME%” from some-path\\play-2.1.a<\/code> to some-path\\play-2.1.b<\/code>.<\/li>\n
  4. To test if everything is ok, open a command line, then execute play version<\/code>. Check if the version displayed is Play! 2.1.B<\/strong>.<\/li>\n<\/ol>\n

    Updating projects<\/h2>\n

    Now that your environment is using the newer version of Play you must update your (Eclipse) project’s imported files.<\/p>\n

      \n
    1. Go to your project’s main folder, open project<\/code> and edit plugins.sbt<\/code>.<\/li>\n
    2. Look for addSbtPlugin(\"play\" % \"sbt-plugin\" % \"2.1.a\")<\/code> and simply change the version to \"2.1.b\"<\/code><\/li>\n
    3. Open a command line on your project’s main folder and run play eclipse<\/code>, just like in the old days. Play startsr to fetch the updated files, remove the old ones and update all those import references. Just sit back while it does all the work.<\/li>\n<\/ol>\n

      Consequences<\/h2>\n

      And it’s done! But mind that… since we replaced the build.bat<\/code> file, the following error will probably reappear:<\/p>\n

      Error occurred during initialization of VM\nCould not reserve enough space for object heap\nError: Could not create the Java Virtual Machine.\nError: A fatal exception has occurred. Program will exit.\n<\/code><\/pre>\n
      You know what to do<\/a>. And since we replaced play.bat<\/code> file, you may also want to add that -DapplyEvolutions.default=true<\/code> argument to the play command (play<\/code> for unix and play.bat<\/code> for windows).<\/p>\n","protected":false},"excerpt":{"rendered":"
