[sleepiq] ClassNotFoundException when communicating with CloudIQ service

[mhilbush]

I'm seeing this error when the binding attempts to authenticate with the CloudIQ service. It's failing on the ClientBuilder class.

Looks like a similar problem to the one @J-N-K fixed in the hdpowerview and neeo bindings.

I'd have a go at fixing this, but I don't know how to tweak Eclipse so that it can deal with his 3rdparty API source code here.
https://github.com/openhab/openhab-addons/tree/main/bundles/org.openhab.binding.sleepiq/src/3rdparty

In Eclipse, all those API classes show as unresolved in the binding classes (such as SleepIQCloudHandler.java). And, as soon as I use Eclipse to edit a source file that references any of those API classes, the binding no longer builds in Maven.

@cweitkamp or @wborn Do you know what I need to do?

[wborn]

If you use the openHAB Eclipse config they should be automatically added to the build path when importing such projects based on the build-helper-maven-plugin config in the POM. In Eclipse you need to have the buildhelper m2e plugin installed for that which was added in: openhab/openhab-distro#1259

You can also add the folders manually to the "Java Build Path" by editing the project properties:

That results in a .classpath file like this:

<?xml version="1.0" encoding="UTF-8"?>
<classpath>
	<classpathentry kind="src" output="target/classes" path="src/main/java">
		<attributes>
			<attribute name="optional" value="true"/>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="src" output="target/classes" path="src/3rdparty/java">
		<attributes>
			<attribute name="optional" value="true"/>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources">
		<attributes>
			<attribute name="maven.pomderived" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="src" output="target/test-classes" path="src/test/java">
		<attributes>
			<attribute name="optional" value="true"/>
			<attribute name="maven.pomderived" value="true"/>
			<attribute name="test" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="src" output="target/test-classes" path="src/3rdparty/test">
		<attributes>
			<attribute name="optional" value="true"/>
			<attribute name="maven.pomderived" value="true"/>
			<attribute name="test" value="true"/>
		</attributes>
	</classpathentry>
	<classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources">

			<attribute name="annotationpath" value="target/dependency"/>
		</attributes>
	</classpathentry>
	<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">

</classpath>

Thanks @wborn!

My Eclipse install is pretty old (about a year, I think), so I suspect I don't have that plug-in. I'll see if I can install that plugin.

[mhilbush]

I got the plug-in installed. But, I still ended up having to hand-edit the classpath. Thanks for posting that - worked perfectly!

[wborn]

Most likely you also need to remove plugin from being ignored in the Maven plugin lifecycle execution.

You can edit that using:

Preferences -> Maven -> Lifecycle Mapping -> Open workspace lifecycle mappings metadata

Then remove the <pluginExecution> section like in the PR and save the file.

[mhilbush]

Good catch. Thank you, Sir!
