title: Installing scala-maven-plugin Manually in Eclipse
body: <p>I want to build a program which needs ScalaIDE. I couldn't install it from its dedicated update site (<a href="http://alchim31.free.fr/m2e-scala/update-site/" rel="nofollow noreferrer">http://alchim31.free.fr/m2e-scala/update-site/</a>) into eclipse, because it was blocked in our region and I can't use it by any filter broker in Eclipse env. so it seems that its installation is useless. 
  I tried some downloaded files from these sites:</p>
  
  <p><a href="http://downloads.typesafe.com/scalaide-pack/4.2.0-vfinal-luna-211-20150928/scala-SDK-4.2.0-vfinal-2.11-win32.win32.x86_64.zip" rel="nofollow noreferrer">http://downloads.typesafe.com/scalaide-pack/4.2.0-vfinal-luna-211-20150928/scala-SDK-4.2.0-vfinal-2.11-win32.win32.x86_64.zip</a></p>
  
  <p><a href="https://github.com/davidB/scala-maven-plugin" rel="nofollow noreferrer">https://github.com/davidB/scala-maven-plugin</a></p>
  
  <p>I installed them by using Help> Install New Software>Add>Archive
  but I couldn't install non of them, because the following error occurs:</p>
  
  <p><a href="https://i.stack.imgur.com/yFEY1.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/yFEY1.jpg" alt="enter image description here"></a></p>
  
  <p>Is there any way to fix this error? How can I install it manually? Which installation file I should use? Could you give me a link, please? I have little experience in Java programming and any help is highly appreciated. </p>
