“NoSuchMethodErrors” due to multiple versions of com.fasterxml.jackson.core:jackson-core

[Bing-ok]

Issue description:

There are multiple versions of com.fasterxml.jackson.core:jackson-core in java-gitlab-api. As shown in the following dependency tree, according to Maven's "nearest wins" strategy, only com.fasterxml.jackson.core:jackson-core:2.5.3 can be loaded, com.fasterxml.jackson.core:jackson-core:2.5.1_ and com.fasterxml.jackson.core:jackson-core:2.9.10 will be shadowed.

However, several methods defined in shadowed version com.fasterxml.jackson.core:jackson-core:2.9.10 are referenced by client project via com.fasterxml.jackson.core:jackson-databind:2.9.10.5 but missing in the actually loaded version com.fasterxml.jackson.core:jackson-core:2.5.3.

For instance, the following missing method(defined in com.fasterxml.jackson.core:jackson-core:2.9.10) are actually referenced by java-gitlab-api, which will introduce a runtime error(i.e., "NoSuchMethodError") into java-gitlab-api.

1. com.fasterxml.jackson.core.JsonParser: com.fasterxml.jackson.core.JsonParser overrideStdFeatures(int,int) is invoked by java-gitlab-api via the following path:

Suggested fixing solutions:

Upgrade direct dependency com.fasterxml.jackson.core:jackson-core from 2.5.3 to 2.9.10. Because version 2.9.10 includes the above missing methods and is compatible with other versions of com.fasterxml.jackson.core:jackson-core in the project.

Thank you very much for your attention. Best regards,
