What Maven dependencies do I need to include Quartz support? Failing with NoClass

Hi,

I'm trying to add quartz scheduling to my app, but am hitting a wall as to which dependencies I need for my pom.xml. According to the Spring maven artifacts page, I need:

Code:

---

                <dependency>
                        <groupId>org.springframework</groupId>
                        <artifactId>spring-context-support</artifactId>
                        <version>3.0.5.RELEASE</version>
                </dependency>

---

But when i try to launch my app, I get the following error message.

Code:

---

Caused by: java.lang.NoClassDefFoundError: org/quartz/CronTrigger
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClassCond(ClassLoader.java:632)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:616)

---

If I try to manually include Quartz 2.0.2 dependency

Code:

---

                <dependency>
                    <groupId>org.quartz-scheduler</groupId>
                    <artifactId>quartz</artifactId>
                    <version>2.0.2</version>
                </dependency>

---

I get the following error message:

Code:

---

Caused by: java.lang.IncompatibleClassChangeError: class org.springframework.scheduling.quartz.CronTriggerBean has interface org.quartz.CronTrigger as super class
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClassCond(ClassLoader.java:632)
        at java.lang.ClassLoader.defineClass(ClassLoader.java:616)

My Job configuration is as follows:

Code:

---

        <bean id="com.funcom.fwl.jobs.BuiltInScheduler" class="org.springframework.scheduling.quartz.SchedulerFactoryBean" scope="singleton">
                <property name="triggers">
                        <list>
                                <!-- trigger list -->
                                <ref bean="fwl.service.TrendLeaderArticleService.trigger" />
                        </list>
                </property>
        </bean>

        <bean id="fwl.service.TrendLeaderArticleService.trigger" class="org.springframework.scheduling.quartz.CronTriggerBean">
                <property name="cronExpression" value="0/30 * * * * ? *" />
                <property name="jobDetail">
                        <bean class="org.springframework.scheduling.quartz.MethodInvokingJobDetailFactoryBean">
                                <property name="name" value="fwl.service.TrendLeaderArticleService" />
                                <property name="group" value="news" />
                                <property name="targetObject" ref="trendLeaderArticleServiceImpl"/>
                                <property name="targetMethod" value="createTrendLeaderArticle"/>
                                <property name="concurrent" value="false" />
                        </bean>
                </property>
        </bean>

Can someone untangle me please and point me in the right direction?

Thanks,

Eric

After a bunch of random trial and error, I discovered that Spring 3.0.5.RELEASE is compatible with Quartz 1.8.5 but not 2.0.

Consequently, need the following dependency in addition to the spring-context-support module :

Code:

---

                <dependency>
                    <groupId>org.quartz-scheduler</groupId>
                    <artifactId>quartz</artifactId>
                    <version>1.8.5</version>
                </dependency>

---

Hope this helps someone else!

Eric

Thanks! it helped me a lot!

thanks saved my time.

Also, try using MAVEN in your project. Maven automatically resolves necessary dependencies. When not sure about the version, check the pom.xml of the module that you're using i.e. spring-context-support. It specifies that spring-context-support depends upon version 1.6.2 of quartz. Since 2.X version of quartz is a major release, including this should be avoided.
