grails 3 jar

[bfmuesli]

I am trying to use this plugin in grails 3, but unfortunately my attempts to build it fail with:

Error initializing classpath: Could not find org.gr8crm.sequence:sequence-generator-starter:0.0.1-SNAPSHOT.

Would it be possible to publish a .jar which I could include in my build.gradle?
The old plugin references:
compile "org.grails.plugins:sequence-generator:1.2"
Since I can't find the newer plugin in grails 3 plugins, I assume it has not yet been published yet.
Any help with this would be greatly appreciated.

What exact version of Grails 3 are you using?
This plugin is dependent on https://github.com/gr8crm/sequence-generator-starter so you could try to clone that repo and run './gradlew install' to install it in your local Maven cache. Then you should be able to compile this plugin.

Thank you for your help with this. This has been a very useful plugin for me in grails 2.

I have updated my app to grails 3 and am now running:
| Grails Version: 3.2.11 | Groovy Version: 2.4.11 | JVM Version: 1.8.0_151
./gradlew install works once I clone the sequence-generator-starter
I ran grails package-plugin successfully after that.
However, once I add the resulting .jar to the lib folder of my project the application won't start anymore.
This happens even if I do not include it via:
compile files("lib/grails-sequence-generator-1.0-SNAPSHOT.jar") in my build.gradle

The error message is rather long but this seems to be at the source of it:

Caused by: org.springframework.beans.BeanInstantiationException: Failed to instantiate [grails.boot.config.GrailsApplicationPostProcessor]: Factory method 'grailsApplicationPostProcessor' threw exception; nested exception is java.lang.NoClassDefFoundError: org/gr8crm/sequence/SequenceConfiguration

at org.springframework.beans.factory.support.ConstructorResolver.instantiateUsingFactoryMethod(ConstructorResolver.java:588)

Caused by: java.lang.NoClassDefFoundError: org/gr8crm/sequence/SequenceConfiguration

Is there something else I am doing wrong here?

Here is how far I got (and a summary for others who might struggle with the same problem):

git clone https://github.com/gr8crm/sequence-generator-starter.git

cd sequence-generator-starter

./gradlew install

cd ../

git clone https://github.com/gr8crm/grails-sequence-generator.git

cd grails-sequence-generator

grails package-plugin

grails install (This was the step I was missing previously)`

after that I can add this to my build.gradle:

compile "grails.plugins.sequence:grails-sequence-generator:1.0-SNAPSHOT"

and the project will start. However if I annotate a domain class with @SequenceEntity it fails with:

startup failed:

Test.groovy: 6: unable to resolve class SequenceEntity ,  unable to find class for annotation
 @ line 6, column 1.
   @SequenceEntity

[bfmuesli]

any pointers as to how to resolve the issue above?

Did the import succeed but the annotation fail?

import grails.plugins.sequence.SequenceEntity

[bfmuesli]

The import succeeds with:
import grails.plugins.sequence.*
After that the annotation will fail
Using your import above it will fail immediately.

[goeh]

So the plugin classes are not on your classpath then. But I can't understand why.

[bfmuesli]

Would you be able to point me to the location of SequenceEntity class in your code.
I seem not to be able to find it in either the sequence-generator-starter nor the grails-sequence-generator.
In the old grails 2 plugin it is located in:
grails-sequence-generator/src/java/grails/plugins/sequence/

[goeh]

Ok, now I've done som research. It turns out that the SequenceEntity annotation is not supported/included in the Grails 3 version of the plugin. :-( I could not get it to work so it's still work in progress and not pushed to github.

[goeh]

I've now pushed my work-in-progress to the branch annotation-wip if you want to give it a try and make it work.
