So I added the following to my build.gradle:
task copyToLib(dependsOn: configurations.default.buildArtifacts, type: Copy)
> {
into('build/output/lib')
from configurations.default
from configurations.default.allArtifacts*.file
}
Then I ran:
$ gradle build
$ gradle copyToLib
Next I tried to run the JAR...
$ cd build\output\lib
$ dir

Could not find the main class: org.mindscratch.foo.ParseMain. Program will
exit.
I'm not sure why it can't find "GroovyObject"...the JAR is in the same
directory as my "foo" jar.
I tried this as well:
$ java -cp . org.mindscratch.foo.ParseMain ....and I get:
Exception in thread "main" java.lang.NoClassDefFoundError:
org/mindscratch/foo/ParseMain
Caused by: java.lang.ClassNotFoundException: org.mindscratch.foo.ParseMain
at java.net.URLClassLoader$1.run(Unknown Source)
I did verify the ParseMain class does exist in my "foo" jar.
Thanks in advance.
