This project reproduces eclipse issue 518218.
The project uses the Jackson parameter names module which relies on Java 8’s -parameters flag.
If you import the project into Eclipse, clean the project and then run either com.example.eclipsebz518218.Application or the com.example.eclipsebz518218.NameTests you’ll see:
Constructor threw exception; nested exception is
com.fasterxml.jackson.databind.exc.InvalidDefinitionException:
Can not construct instance of com.example.eclipsebz518218.Name
(no Creators, like default construct, exist): can not deserialize from Object value (no delegate- or property-based Creator)
at [Source: (byte[])"{"first":"Fred", "last":"Bricon"}"; line: 1, column: 2]
If you right click on the project, select Properties → Java Compiler and check "Store information about method parameters (usable via reflection)" the problem goes away.
Unfortunately Maven → Update Project… will cause the setting to be unchecked again.
If you build from the command line the tests pass, you can also run java -jar target/eclipsebz518218-1.0.0-SNAPSHOT.jar without issue.
