Fresh Forge Eclipse Workspace - 8 warnings right off the bat

[Taji34]

Forge Version: minecraftforge-src-1.6.2-9.10.0.789

Eclipse Version: Kepler Release (Build id: 20130614-0229)

JDK Version: jdk1.7.0_09

 

Okay, so I followed the tutorial on the wiki, and when I open my workspace it has the following 8 warnings:

• Build path specifies execution environment JavaSE-1.6. There are no JREs installed in the workspace that are strictly compatible with this environment.
  
• Dead code
  
• Resource leak: '<unassigned Closeable value>' is never closed
  
• Resource leak: 'jar' is never closed
  
• Resource leak: 'mcJarFile' is never closed
  
• The argument of type String[] should explicitly be cast to Object[] for the invocation of the varargs method translateToLocalFormatted(String, Object...) from type StatCollector. It could alternatively be cast to Object for a varargs invocation
  
• The assignment to variable par2 has no effect
  
• Unreachable catch block for IOException. Only more specific exceptions are thrown and they are handled by previous catch block(s).
  

 

I have not done anything to any files yet, this is off a clean install. Should I worry about these warnings, or not? Thank You.

Code doesn't always decompile cleanly and Minecraft isn't the best written.

 

You can ignore these,

errors would be from a bad decompile and you need to do it again,

 

Most warnings are pre-ignored with filters, by disabling them a clean minecraft decomple has about 3500 warnings

Okay, just wondering, thanks!
