Null TemplateRenderer in BaseBuildConfigurationAwarePlugin sub-class when using Spring Scanner

[Chris Cormack]

I have a pretty simple Bamboo plugin that was created using 'atlas-create-bamboo-plugin', however, now that I am adding some configuration I am hitting a null pointer due to 'getTemplateRenderer()' in 'BaseBuildConfigurationAwarePlugin' returning 'null'.

I have this in 'atlassian-plugin.xml':

<additionalBuildConfigurationPlugin key="configuration" class="com.orgname.bamboo.githubStatus.Configuration">
    <resource type="freemarker" name="edit" location="config/edit.ftl" />
</additionalBuildConfigurationPlugin>

and com.orgname.bamboo.githubStatus.Configuration is implemented as:

package com.orgname.bamboo.githubStatus;

import com.atlassian.bamboo.plan.Plan;
import com.atlassian.bamboo.plan.cache.ImmutablePlan;
import com.atlassian.bamboo.plan.configuration.MiscellaneousPlanConfigurationPlugin;
import com.atlassian.bamboo.v2.build.BaseBuildConfigurationAwarePlugin;

public class Configuration extends BaseBuildConfigurationAwarePlugin implements MiscellaneousPlanConfigurationPlugin {
    @Override
    public boolean isApplicableTo(@NotNull ImmutablePlan immutablePlan) {
        return true;
    }
}

I have tried overriding 'getEditHtml()' to track down that the NPE is happening in this line (and that getTemplateRenderer() is returning null):

return this.getTemplateRenderer().render(templatePath, context);

By way of experiment, I have tried adding this to my Configuration class:

@Inject
private TemplateRenderer myInternalRenderer;

and this fails with:

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'com.orgname.bamboo.githubStatus.Configuration': Unsatisfied dependency expressed through field 'myInternalRenderer'; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'com.atlassian.bamboo.template.TemplateRenderer' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {@javax.inject.Inject()}

I am not sure where to take this from here, so any suggestions very much appreciated.

Hi @Chris Cormack,

App development related questions are best asked in the Atlassian Developer Community, you have a greater chance to get feedback from other app developers there.

The question at hand seems to be appropriate for the Atlassian Developer Tools category, even though there is also a Bamboo Development category for solely Bamboo related questions. 

• To set expectations regarding the latter, you'll note that there are comparatively few Bamboo related questions - regardless, quite some Atlassian team members are monitoring the community by now, so hopefully they can loop in someone from the Bamboo team.

Cheers,

Steffen
