I just experienced this myself with Play 2 and it turns out it wasn't truly hanging, it was just pulling a maven and downloading the Internet. To verify this is the same behavior you were experiencing edit <code>project/plugins.sbt</code> and replace:

<pre><code>logLevel := Level.Warn
</code></pre>

with

<pre><code>logLevel := Level.Debug
</code></pre>

(Though I am building on OSX I imagine you will experience similar output on Windows.)

Try aborting your build, deleting the referenced lock file then doing a 'play run' again.

Just to add to existing answer here,

I am also seeing this behaviour after I upgraded from Play 2.2x to Play 2.3.x ( see <a href="http://www.playframework.com/documentation/2.3.x/Migration23" rel="nofollow">MigrationGuide</a> )

I was debugging as follows below.

On Linux, goto your project folder and then:

<pre><code>$ bash -x `which sbt`
.... OUTPUT SKIPPED....
++ (( 128 &lt; 512 ))
++ local 'common_opts=-Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m'
++ [[ 1.7.0_55 &lt; 1.8 ]]
++ local perm=256
++ echo '-Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m'
+ execRunner java -Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m -jar /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar
+ [[ -n '' ]]
+ [[ -n '' ]]
+ java -Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m -jar /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar
</code></pre>

Note down the command in last line, cancel the current process <code>Ctrl+C</code>, and execute it adding <code>-verbose</code> option to <code>java</code>:

<pre><code>java -verbose -Xms1024m -Xmx1024m -XX:ReservedCodeCacheSize=128m -XX:MaxPermSize=256m -jar /usr/share/sbt-launcher-packaging/bin/sbt-launch.jar
</code></pre>

Finally I also added <code>logLevel := Level.Debug</code> in <code>project/plugins.sbt</code>.

However, it keeps giving output like this:

<pre><code>.... OUTPUT SKIPPED....

There appears to be too many jars to be downloaded. I am now using offline version of Typesafe Activator ( 356MB download <a href="http://www.playframework.com/download" rel="nofollow">here</a> ), and this is so much faster!

I am just getting started with Play Framework. I have downloaded and installed play and created a sample java application. When I try to start the play console in the application directory it hangs at "Loading project definition".

<pre><code>PS C:\dev\play\javatest&gt; play.bat
Getting org.scala-sbt sbt_2.9.1 0.11.3 ...
:: retrieving :: org.scala-sbt#boot-app
 confs: [default]
 37 artifacts copied, 0 already retrieved (7245kB/283ms)
[info] Loading project definition from C:\dev\play\myFirstApp\project
</code></pre>

When i try running a Scala application i get a message about it waiting for a lock:

<pre><code>PS C:\dev\play\scalatest&gt; play
[info] Loading project definition from C:\dev\play\test1\project
Waiting for lock on C:\lib\play\repository\.sbt.ivy.lock to be available...
</code></pre>

Running Windows 7, JDK 1.7.0_05 and Play Framework 2.0.2. Any ideas?

Play framework hangs on startup at: "Loading project definition from"
