【问题描述】：

我正在 Tomcat 7.0.23 中部署多个 Grails (1.3.7) 应用程序。我的 *.jar 文件位于 shared/lib 而不是 WEB-INF/lib 中。我在日志文件中看到了下一个输出：

在 Google 中搜索我找到了a post，其中提出了解决方案。

解决方案在服务器/项目 jar 中查找重复项。就我而言 spring JSTL 具有 Spring 标准的依赖，消除了第二个解决了问题（第二个再次包含相同的 TLD）

>                 <dependency>
>             <groupId>javax.servlet</groupId>
>             <artifactId>com.springsource.javax.servlet.jsp.jstl</artifactId>
>             <version>1.2.0</version>
>             <exclusions>
>              <exclusion>
>               <artifactId>com.springsource.org.apache.taglibs.standard</artifactId>
>               <groupId>org.apache.taglibs</groupId>
>              </exclusion>
>             </exclusions>
>             </dependency>

但是，我不知道如何在 grails 应用程序中应用指定的解决方案。欢迎任何帮助。

【解决方案1】：

您可以在 BuildConfig.groovy 中排除 Grails 应用程序中的传递依赖项

grails.project.dependency.resolution = {

    // inherit all Grails' default dependencies except xml-apis
    inherits("global") {
        excludes 'xml-apis'
    }

    // dependency on jsoup that excludes transitive dependency on foo 1.0.0
    compile 'org.jsoup:jsoup:1.6.1' {
        excludes 'org.jsoup:foo:1.0.0'
    }
}
