Plugin initialization problem
MavenHello,
one of user of our extenstion (cutom developed for him) has problem with loading it. It works properly on our computers but not on his. He has the same version of the RapidMiner Studio (we tried 7.1 and 7.2). The only differrence is installed plugins.
When RM starts this error appears:
This is part of starting log with the error:

/**

*/

Thank you for any advice.

Hi,
this looks extremely weird and I have never seen this before. Can your customer please:
1. Install RapidMiner Studio into a fresh folder (NOT into an existing installation) and try again with that one?
or if that does not work:
2. Close Studio, rename his .Rapidminer folder and try again.
Regards,
Marco
Hi Marco,
thank you. He tried it and the problem persists.
What can we do next? Should I connect you with the customer? Or do you have any other idea?
Best wishes,
Vaclav
Hi,
how does your build.gradle look like? This error is extremely weird.
Regards,
Marco
Hello,
the gradle sript looks like this:
buildscript {
repositories {
jcenter()
maven { url 'https://maven.rapidminer.com/content/groups/public/' }
}
}
plugins { id 'com.rapidminer.extension' version '0.8.2' }
// Define Maven artifact repositories
repositories {
jcenter()
maven { url 'https://maven.rapidminer.com/content/groups/public/' }
}
extensionConfig {
// The extension name
name 'Invoices'
/*
* The artifact group which will be used when publishing the extensions Jar
* and for package customization when initializing the project repository.
*
* It is 'com.rapidminer.extension' by default.
*/
groupId = 'com.burgsys.invoices'
/*
* The extension vendor which will be displayed in the extensions about box
* and for customizing the license headers when initializing the project repository.
*
* It is 'RapidMiner GmbH' by default.
*/
vendor = "Burgsys, a. s."
/*
* The vendor homepage which will be displayed in the extensions about box
* and for customizing the license headers when initializing the project repository.
*
* It is 'www.rapidminer.com' by default.
*/
homepage = "www.burgsys.com"
// define RapidMiner version and extension dependencies
dependencies {
rapidminer '7.1.0'
//extension namespace: 'text', version: '6.1.0'
}
}
// Define third party library dependencies
dependencies {
compile 'net.imagej:ij:1.51d'
compile 'org.apache.pdfbox:pdfbox:2.0.2'
compile 'org.apache.pdfbox:pdfbox-tools:2.0.2'
compile 'net.sf.trove4j:trove4j:3.0.3'
compile 'net.sourceforge.tess4j:tess4j:3.2.1'
}
It is standard build.gradle with few added libraries.
Best wishes,
Vaclav
I have the same problem since I updated RapidMiner to 7.2.001 with another Plugin, namely RapidProm. Although I have got the newest version of that as well (3.0.7)
Hi Grace,
We (RapidProM dev. team) are aware of the incompatibility of 3.0.7 with RM 7.2+
We are working on a new version 4.0.0 which will be RM7.2+ compatible.
We are planning to release it in the beginning of next week.
kind regards,
Bas.
