Gradle clean<customTask> not working - gradle

Question

I have a custom task to do a Websphere EJBDeploy. I have defined the inputs and ouputs, and get successful incremental compilation, but I can't get the automatically generated clean task to work properly.
According to docs, for a custom task named "ejbDeploy" with a defined output, a cleanEjbDeploy task should be automatically generated.
Pattern: clean<TaskName>: Cleans the output files of a task.
So here's my custom task:
task ejbDeploy(dependsOn: 'jar'){
srcFile = file(jar.archivePath)
destDir = new File("build/ejbDeploy")
inputs.file srcFile
outputs.dir destDir
def cp = project.files(
project.sourceSets.main.output.classesDir,
project.sourceSets.main.resources,
project.configurations.runtime
).getAsPath()
doLast{
destDir.mkdirs()
exec{
executable = wasEjbDeploy
workingDir = destDir
args = [
jar.archivePath,
".",
jar.archiveName,
"-cp",
cp
]
}
}
}
Anyone have any ideas as to why the clean rule isn't working?
[Edit]
Here's the full (anonymized) file contents (this has changed since initial question post):
version = '1.0-SNAPSHOT'
group = 'com.company'
buildscript {
repositories {
mavenLocal()
mavenCentral()
}
dependencies {
classpath group: 'name.benjaminAbbitt', name: 'WASEjbDeploy', version: '1.0-SNAPSHOT'
}
}
apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'base'
repositories {
mavenCentral()
mavenLocal()
}
dependencies {
compile 'javax.mail:mail:1.4.5'
compile 'log4j:log4j:1.2.16'
compile files(fileTree(dir: 'lib', includes: ['*.jar']) )
}
task ejbDeploy(type:name.benjaminAbbitt.WASEjbDeploy, dependsOn: 'jar'){
wasEjbDeployPath = wasEjbDeploy
}

The clean rule is provided by the base plugin. Since many other plugins (e.g. java) already apply the base plugin, you typically don't have to apply the base plugin yourself. But in case:
apply plugin: "base"
