JxlsException: Method createTransformer of org.jxls.transform.poi.PoiTransformer null

[daliadaud]

Hi, anybody still facing this issue ?
For context, I'm using
jxls-poi 2.13.0
jxls 2.13

		<dependency>
			<groupId>org.jxls</groupId>
			<artifactId>jxls</artifactId>
			<version>2.13.0</version>
		</dependency>
		<dependency>
			<groupId>org.jxls</groupId>
			<artifactId>jxls-poi</artifactId>
			<version>2.13.0</version>
		</dependency>

Do we need to explicitly specify the poi in our pom.xml?
And the biggest issue is that the problem comes and goes each time we build the code

oddly enough the stack trace does not reflect the code base from 2.12 or 2.13 of PoiTransformer

stack trace
at org.jxls.transform.poi.PoiTransformer.createTransformer(PoiTransformer.java:150)
at org.jxls.transform.poi.PoiTransformer.createTransformer(PoiTransformer.java:141)
at org.jxls.transform.poi.PoiTransformer.createTransformer(PoiTransformer.java:122)

createTransformer for 2.12 and 2.13 are at lines :

is the version updated in maven?

Are Apache POI jar's in the class-path?
