Comparing two versions of the guava library

In the following you see some of the differences between the versions 18.0 and 19.0 of Google's guava library. The differences between the two Java APIs are also printed on the command line for a quick overview. Please note that binary incompatible changes are flagged with an exclamation mark (!) while source incompatible changes are marked with a trailing star (*).

Optionally japicmp can also create an HTML report. An example for such a report can be found here:

HTML Report

At your preference, japicmp can generate a Markdown report. You can see an example here.

Markdown Report

You can also let japicmp create an XML report like the following one:

Tracking changes of an XML document marshalled with JAXB

The following output shows the changes of a model class with some JAXB bindings:

***  MODIFIED CLASS: PUBLIC japicmp.test.jaxb.SimpleDocument
	***  MODIFIED METHOD: PUBLIC java.lang.String getTitle()
		---  REMOVED ANNOTATION: javax.xml.bind.annotation.XmlAttribute
		+++  NEW ANNOTATION: javax.xml.bind.annotation.XmlElement
	***  MODIFIED METHOD: PUBLIC java.lang.String getAuthor()
		---  REMOVED ANNOTATION: javax.xml.bind.annotation.XmlAttribute
		+++  NEW ANNOTATION: javax.xml.bind.annotation.XmlElement
	***  MODIFIED ANNOTATION: javax.xml.bind.annotation.XmlRootElement
		***  MODIFIED ELEMENT: name=document (<- simpleDocument)

As can bee seen from the output above, the XML attributes title and author have changed to an XML element. The name of the XML root element has also changed from “simpleDocument” to “document”.
