Vision Module Faulting on startup due to Other Module Loaded

Module Development
,
1

Currently developing a module, and for some reason having it loaded onto the gateway causes Vision to fault on startup. Uninstalling it and restarting Vision works fine.

I recently added more dependencies to maven for Alarming, Reporting and Vision. Something to do with class or module loaders or version inconsistency? This line specifically is suspect:

com.inductiveautomation.factorypmi.common.projectprops.LaunchProps cannot be cast to class com.inductiveautomation.factorypmi.common.projectprops.LaunchProps

I assume modules shouldn't affect each other like this, why I put as a bug. Here's the errors and logs the error generates:

Are you sure that's the right version of the Vision module for that gateway version? (Must match.)

3

Modules on the gateway are loaded into isolated classloaders specifically to prevent collisions like this. Unless you marked them as depending on each other, in which case they'll get shared silos.

My guess is that your dependency declaration is incorrect - if you look in your built .modl file, does it actually include Vision module artifacts? In general, but especially if those are the wrong version (per Phil's comment), that's going to cause problems. Your module file must only include its own internal dependencies.

Includes this:

Not sure why there are two versions listed

Here's what I got in the poms:

 <dependency>
    <groupId>com.inductiveautomation.ignitionsdk</groupId>
    <artifactId>vision-common</artifactId>
    <version>8.1.43</version>
    <type>pom</type>
 </dependency>

in client:

<dependency>
    <groupId>com.inductiveautomation.ignitionsdk</groupId>
    <artifactId>vision-designer-api</artifactId>
    <version>${ignition-sdk-version}</version>
    <type>pom</type>
    <scope>provided</scope>
 </dependency>

in designer:

<dependency>
    <groupId>com.inductiveautomation.ignitionsdk</groupId>
    <artifactId>vision-designer-api</artifactId>
    <version>${ignition-sdk-version}</version>
    <type>pom</type>
    <scope>provided</scope>
 </dependency>
5

I don't know what folder I'm looking at there, but all your module-related compilation dependencies need to be provided, since they'll be...provided, by the module you're depending on.

6

Thats the .modl file unzipped

7

Not a Maven guy, so I can't help you exactly with what to change, but none of those should be there. Your .modl file should only contain your module's direct artifacts (your own -common, -client, -designer, , -gateway jars, plus third party dependencies your module relies on, if any). Nothing provided by Ignition should be there.

Are you using an old version of the Maven module plugin?

8

Hm, that doesn't seem to work as it can't find the symbols for compilation without having the dependencies in maven. Should everything just be available by default?

9

You need to set IA's stuff to be compile-only dependencies. (Sorry, I don't use maven, so cannot be specific.)

10

This one is your problem. It's not <scope>provided</scope> like the others.

11

seemed to do the trick, also got rid of vision-common as a dependency in the common pom
