We have to move our project back to GWT 2.7 due to some java 1.8 issues. I've checked all my jar files to make sure they are 2.7 and no duplicate jars in the build path but am getting errors when I try to compile with Ant.

Any suggestions would be greatly appreciated. Thank you.

[java] Caused by: java.lang.NoSuchMethodError: com.google.gwt.util.tools.Utility.close(Ljava/lang/AutoCloseable;)V

[java] at com.google.gwt.resources.rg.ImageResourceGenerator.getContentLength(ImageResourceGenerator.java:623)

This close(AutoCloseable) method was added in 2.8: https://github.com/gwtproject/gwt/commit/349210a31ec593cb499ac73a80743b89bd8d5aac

So this means you have gwt-user from 2.8 and gwt-dev from 2.7 here.
