Expose filename from `input` step

[jglick]

#105 (comment)

If I recall correctly how #30 works,

file-parameters-plugin/src/main/java/io/jenkins/plugins/file_parameters/Base64FileParameterValue.java

Line 50 in 720ae16

filename = file.getName();

or

file-parameters-plugin/src/main/java/io/jenkins/plugins/file_parameters/AbstractFileParameterDefinition.java

Line 77 in 720ae16

p.filename = src.getName();

would record filename information but the input step will only call

file-parameters-plugin/src/main/java/io/jenkins/plugins/file_parameters/Base64FileParameterValue.java

Lines 70 to 72 in 720ae16

	@Override public Object getValue() {
	return base64;
	}

which ignores it;

file-parameters-plugin/src/main/java/io/jenkins/plugins/file_parameters/AbstractFileParameterValue.java

Line 97 in 720ae16

env.put(name + "_FILENAME", filename);

only applies to build parameters. Perhaps Base64FileParameterDefinition could have an option for getValue to expose a wrapper object or Map which encodes the Base64-encoded value, the raw value, and (when available) the filename.

workaround:

String getFilename( String paramName ) {
  env.getEnvironment().find{ "${paramName}_FILENAME" == it.key }?.value ?: ''
}

Hello, is there any update on this issue?
