5.x "Cannot determine ID or path from provided Integer instance, must be Long, String, or a Project instance"

[tkruse]

In gitlab4j 5.3.0, AbstractAPI accepts only Long since cf58df4

This causes unnecessary breakage for client who have passed integer Ids to any api, such as

public Pipeline triggerPipeline(Object projectIdOrPath, String token, String ref, List<Variable> variables) 

Example code:

final int MY_PROJECT_ID = 1234;
var pipelineApi = gitLabApi.getPipelineApi();
pipelineApi.triggerPipeline(projectId, token, ref, variables)

Exception:

java.lang.RuntimeException: Cannot determine ID or path from provided Integer instance, must be Long, String, or a Project instance
    at org.gitlab4j.api.AbstractApi.getProjectIdOrPath(AbstractApi.java:62)
    at org.gitlab4j.api.PipelineApi.triggerPipeline(PipelineApi.java:812)

While I appreciate Ids can be long in the future, the weird code in getProjectIdOrPath() could continue to accept both Integer and Long, so I suggest something like:

  } else if (obj instanceof Long) {
    return (obj);
+    } else if (obj instanceof Integer) {
+      // Gitlab4j <5.x compatibility
+      return (obj);

Probably in case of an Integer we could turn it to Long and this would preserve the backward compatibility you are looking for.

Probably this could be done in all methods modified with cf58df4 to stay consistent.
