我正在尝试将Grails和Maven集成到现有的grails项目中。
但这引发了异常

maven-test (default) on project Co-optimum: Unable to start Grails:    java.lang.reflect.InvocationTargetException: org/springframework/security/web/authentication/LoginUrlAuthenticationEntryPoint: org.springframework.security.web.authentication.LoginUrlAuthenticationEntryPoint

请您参考如下方法:

Maven集成已在Grails 2.1.0中进行了重新设计，并且现在还需要在Maven pom文件中定义插件依赖项。以前，插件依赖项是使用BuildConfig.groovy或application.properties管理的。

您需要将所有插件和常规依赖项从BuildConfig.groovy和application.properties移至pom.file。

对于某些插件，可能需要使用标准Grails在pom中显式添加不需要的依赖项。但是从Maven启动Grails时，从错误日志中可以清楚地看出这一点。

具体来说，您缺少对Spring安全性插件的依赖关系，需要将以下XML片段添加到依赖关系列表中:

       <dependency> 
            <groupId>org.grails.plugins</groupId> 
            <artifactId>spring-security-core</artifactId> 
            <version>1.2.7.3</version> 
            <scope>compile</scope> 
            <type>zip</type> 
        </dependency>
