Spring XD Dynamic Module ClassLoader Issue - classloader

Question

According to the documentation we can load jars dynamically at module creation time by exploiting the attribute module.classloader in the .properties file :
http://docs.spring.io/spring-xd/docs/1.3.1.RELEASE/reference/html/#module-class-loading
I spent two days trying to test this feature. It does not work. The option module.classloader seems to be simply ignored
I did not find any string named module.classloader in the XD code. But I found another one called module.classpath in this class:
https://github.com/spring-projects/spring-xd/blob/master/spring-xd-module/src/main/java/org/springframework/xd/module/options/ModuleUtils.java
The code in the above class seems to match the documentation. But unfortunalletely it does not work too. My classes are not found and I get java.lang.ClassNotFoundException
I have module option named dir4jars where I put the jars to load at creation time (when I issue job create --name xx --defintion ..). It's a directory, and I have tested the following possibilities, with both module.classpath and module.classloader :
module.classpath=${dir4jars}/*.jar
module.classloader=${dir4jars}/*.jar
.
.
job create --name jobName --definition "myJobModuleName --dir4jars=C:/ELS/Flash/libxd" --deploy
and
job create --name jobName --definition "myJobModuleName --dir4jars=file:C:/ELS/Flash/libxd" --deploy
I need the dir4jars to be absolute and outside XD home.
So my questions:
What's the right option to use for this dynamic load? module.classpath or module.classloader ?
How can I set an absolute directory as I mentioned above?
Many thanks.

Answer 1

I think it has to be module.classpath and module.classloader looks like a mistake in the documentation. Does this work when you explicitly use module.classpath=file:C:/ELS/Flash/libxd?
As a side note: Please consider using Spring Cloud Data Flow which is the successor of Spring XD.
