Hello everyone.
I am a new comer for Spark plugin development, so my first step is to try the simplest thing: copy “example.jar” provided by the development guide into my spark/plugin driectory.
But oops… nothing happen…WHY??
I run Spark 2.6.3 on windows vista. Many thanks to anyone who pays attention to this post.
look at the log files
Thank you!
According to your advise, I view error.log in \logs. Something strange happens.
The log shows an error:“Unable to load plugin com.mypackage.ExamplePlugin.”
However, there are no jar file in \plugins directory called “com.mypackage.ExamplePlugin”.
The example plugin I dropped into the directory is “com.jivesoftware.spark.examples.ExamplePlugin”
It seems that Spark is looking for a not-existing plugin, while my plugin ignored…
Check your plugin.xml file
Excuse me for the bothering…
I had uninstalled Spark, deleted directory “spark” and everything in it, and reinstall Spark software, but when I ran the new Spark, the same error “Unable to load plugin com.mypackage.ExamplePlugin.” showed up again.
I had NOT drop any self-developed plugin into the directory, it was a completely new,clean installation.
Do spark “memorize” what plugin “should” be loaded somewhere other than install directory? many thanks.
remove example.jar and the example folder from
%APPDATA%/Spark/plugins
