This happens when I click on the Edit button on Builder Configuration.
java.io.FileNotFoundException: Template templates/plugins/builder/antBuilderedit.ftl not found. at freemarker.template.Configuration.getTemplate(Configuration.java:488) at freemarker.template.Configuration.getTemplate(Configuration.java:458) at com.atlassian.bamboo.ww2.BambooFreemarkerManager.renderPage(BambooFreemarkerManager.java:88) at com.atlassian.bamboo.ww2.BambooFreemarkerManager.render(BambooFreemarkerManager.java:115) at com.atlassian.bamboo.builder.AbstractBuilder.getFreemarkerEditHtml(AbstractBuilder.java:144) at com.atlassian.bamboo.ww2.actions.build.admin.ConfigureBuildBuilder.getEditHtml(ConfigureBuildBuilder.java:183) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:585) at freemarker.ext.beans.BeansWrapper.invokeMethod(BeansWrapper.java:616) at freemarker.ext.beans.SimpleMethodModel.exec(SimpleMethodModel.java:113) at freemarker.core.MethodCall._getAsTemplateModel(MethodCall.java:93) at freemarker.core.Expression.getAsTemplateModel(Expression.java:89) at freemarker.core.Expression.getStringValue(Expression.java:93) at freemarker.core.DollarVariable.accept(DollarVariable.java:76) at freemarker.core.Environment.visit(Environment.java:196) at freemarker.core.MixedContent.accept(MixedContent.java:92) at freemarker.core.Environmen
