jackson-annotations are not included as a dependency within jackson-dataformat-csv

[FortisJoe]

When I attempt to use jackson-dataformat-csv from maven as follows:

<dependency>
        <groupId>com.fasterxml.jackson.dataformat</groupId>
        <artifactId>jackson-dataformat-csv</artifactId>
        <version>2.7.0</version>
</dependency>

I encounter the following error:

java.lang.NoClassDefFoundError: com/fasterxml/jackson/annotation/JsonInclude$Value

at com.fasterxml.jackson.databind.cfg.MapperConfig.<clinit>(MapperConfig.java:45)
at com.fasterxml.jackson.databind.ObjectMapper.<init>(ObjectMapper.java:535)
at com.fasterxml.jackson.databind.ObjectMapper.<init>(ObjectMapper.java:461)
at com.fasterxml.jackson.dataformat.csv.CsvMapper.<init>(CsvMapper.java:44)
at com.fasterxml.jackson.dataformat.csv.CsvMapper.<init>(CsvMapper.java:39)

Adding the following resolves this issue:

     <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-annotations</artifactId>
        <version>2.7.0</version>
    </dependency>

Hmmh. Ok, yes, introduction of value objects in jackson-annotations did make it a required dependency, not optional...

[cowtowncoder]

Actually. Hmmh. No... the problem is not so much missing annotations, but more likely old version.
As far as I can see, CSV module does not directly depend on JsonInclude.Value, but jackson-databind does. It should (and does) have dependency on jackson-annotations.
What may happen is that version of annotations is older: JsonInclude.Value was added in 2.6. But I don't know how/why such version would be included -- maybe you can see what mvn dependency:tree says?

Now: I am open to improvements that could help, and perhaps direct addition of annotations makes sense. This because jackson-databind is a hard dependency (not "provided"), so annotations are needed no matter what.

Having had a look at the results of mvn dependency:tree things get interesting:

Removing the dependency on zauber:okta-sdk-wrapper:jar:1.0-SNAPSHOT:compile results in the following:

[INFO] - com.fasterxml.jackson.core:jackson-annotations:jar:2.7.0:compile

Which is correct behavior.

Checking out a branch of the 2.7.0 release and removing the test scope from the jackson-annotations dependency, while reintroducing the zauber:okta-sdk-wrapper:jar:1.0-SNAPSHOT:compile dependency results in the following:

[INFO] zauber:user-import:jar:1.0-SNAPSHOT

Which confirms to me that the fix introduced in 34f405d works.

Many thanks!

@zauberjoe thank you for verifying this.
