Configuring ObjectMapper with gradle

[Thom Hehl]

I am using gradle for my first project and am trying to bring down the correct jackson. Here is the entry from my build.gradle file.

    compile("com.fasterxml.jackson.core:jackson-core:2.5.4")

I run the build and try to reference ObjectMapper and eclipse can't find it. I went to the core library and it doesn't seem to contain ObjectMapper.

Obviously, I'm running from out of date docs, but no idea how to proceed.

Thanks.

Ah. jackson-core contains streaming parser (JsonParser), generator (JsonGenerator) and factory to create those (JsonFactory). It is a small lib to allow low-level usage with minimal overhead.

ObjectMapper comes from `jackson-databind`, which depends on `jackson-core` and `jackson-annotations`.

So you need to add `jackson-databind` at least, `jackson-annotations` should be pulled in as a dependency (although you may want to be explicit to ensure identical minor version).

Hope this helps,
