Java error compiling NormalizedZipInputStream in updater/src/com/intellij/updater/Utils.java

Hello

I want to build my first plugin for IntelliJ, and following the instruction here http://www.jetbrains.org/intellij/sdk/docs/basics/getting_started/setting_up_environment.html it seems that I should have community edition source code built. I'm trying to, with this guide http://www.jetbrains.org/intellij/sdk/docs/basics/checkout_and_build_community.html .

I have not added /lib/tools since I'm on mac.

At the point : "Use Build | Make Project to build the code", I have a compilation error :

Error:(278, 18) java: no suitable method found for sort(java.util.List<capture#1 of ? extends java.util.zip.ZipEntry>,java.util.Comparator<java.util.zip.ZipEntry>)
    method java.util.Collections.<T>sort(java.util.List<T>) is not applicable
      (cannot infer type-variable(s) T
        (actual and formal argument lists differ in length))
    method java.util.Collections.<T>sort(java.util.List<T>,java.util.Comparator<? super T>) is not applicable
      (cannot infer type-variable(s) T,T,U
        (argument mismatch; java.util.Comparator<capture#1 of ? extends java.util.zip.ZipEntry> cannot be converted to java.util.Comparator<? super capture#1 of ? extends java.util.zip.ZipEntry>))

I'm using javac 1.8.0_25 on MacOsX 10.12

It seems that the type of myEntries is not confirm to the sort function...  I tryed some modification, but I know too little about the project.

Can someone help me please.

Thanks
