frontend-maven-plugin: yarn run stuck

Hi,

I’m trying to run a script with yarn run

<execution>
 <id>yarn run build</id>
  <goals>
   <goal>yarn</goal>
  </goals>
  <configuration>
  <arguments>run build</arguments>
  </configuration>
</execution>

But the process is stuck when running the script :

[INFO] yarn run v0.21.3
[INFO] $ ng build 

And then nothing.

When I manually run the command, it works fine.

I use :

• Windows 7
• maven 3.3.9
• Java 7
• Node v6.9.5
• yarn v.0.21.3

It works fine if I use npm
