I need to create 3 new custom field types. Can someone help?

[Chad]

I have recently finished the tutorial on how to create a basic Jira plugin and have started experimenting with creating new custom field types.

Currently using this documentation:

https://developer.atlassian.com/server/jira/platform/creating-a-custom-field-in-jira/
https://developer.atlassian.com/server/jira/platform/custom-field/

Our team has a need to create three new custom field types that do not store any data in the history/change logs.

1. A New Custom Text Field type

2. A New Custom Date/Time Field type

3. A New Custom Number Field type

It is also a requirement that these fields must be searchable.

So far I have been successful in creating the custom text field (not sure how to make it searchable), but the number and date/time fields are proving to be a struggle.

Here is the code I have for the text field:

import com.atlassian.jira.issue.customfields.impl.GenericTextCFType;
import com.atlassian.jira.issue.customfields.manager.GenericConfigManager;
import com.atlassian.jira.issue.customfields.persistence.CustomFieldValuePersister;
import com.atlassian.jira.issue.fields.CustomField;
import com.atlassian.jira.issue.fields.TextFieldCharacterLengthValidator;
import com.atlassian.jira.security.JiraAuthenticationContext;
import com.atlassian.plugin.spring.scanner.annotation.component.Scanned;
import com.atlassian.plugin.spring.scanner.annotation.imports.JiraImport;

@Scanned
public class TextCustomField extends GenericTextCFType {

    public TextCustomField(
            @JiraImport CustomFieldValuePersister customFieldValuePersister,
            @JiraImport GenericConfigManager genericConfigManager,
            @JiraImport TextFieldCharacterLengthValidator textFieldCharacterLengthValidator,
            @JiraImport JiraAuthenticationContext jiraAuthenticationContext) {
        super(customFieldValuePersister, genericConfigManager, textFieldCharacterLengthValidator , jiraAuthenticationContext);
    }

    @Override
    public String getChangelogValue(CustomField field, String value) {
        // No log into history tab
        return null;
    }
}

Any advice for creating the other two field types would be greatly appreciated!

Thanks!

Using the JIRA source code as a guide has helped me to get most of this done. I was able to pull the TextCFType.java, NumberCFType.java, and DateTimeCFType.java files from it along with the corresponding searcher classes.

I still haven't figured out how to get the searcher working for the Date/Time field because maven dependencies are a pain and the public Jira API doesn't seem to include all of the necessary class imports. If anyone has a good solve for this I'd love to hear it.
