Question

我必须使用Cisco的第三方Java API，它使用旧版本的Log4J，即1.1.3 当独立运行时，显然API工作正常，但是当从Grails（1.3.7）运行时，它在Log4j初始化期间崩溃并出现一些“未找到操作”异常。

如何解决此冲突？

这是BuildConfig实际插件，其中包含lib文件夹中的cisco lib。

grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
//grails.project.war.file = "target/${appName}-${appVersion}.war"
grails.plugin.location.'advoss-orm-core' = "../../../advoss-orm-core-grails-plugin/branches/ShahbazORMPlugin"

grails.project.dependency.resolution = {
    // inherit Grails' default dependencies
    inherits("global") {
        // uncomment to disable ehcache
        // excludes 'ehcache'
    }
    log "warn" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
    repositories {
        grailsPlugins()
        grailsHome()
        grailsCentral()

        // uncomment the below to enable remote dependency resolution
        // from public Maven repositories
        mavenLocal()
        mavenCentral()

        flatDir  name:"lib", dirs:"lib"
        //mavenRepo "http://snapshots.repository.codehaus.org"
        //mavenRepo "http://repository.codehaus.org"
        //mavenRepo "http://download.java.net/maven/2/"
        //mavenRepo "http://repository.jboss.com/maven2/"
    }
    dependencies {
        runtime('mysql:mysql-connector-java:5.1.16') {
            transitive = false
        }
        compile ':command:1.0',
                ':commons-codec:1.3',
                ':commons-httpclient:3.1',
                ':commons-logging:1.1.1',
                ':deltawing:1.0',
                ':deltaxml:1.0',
                ':isorelax:1.0',
                ':jhall:1.0',
                ':jing:1.0',
                ':junit-dep:4.9b2',
                ':marklogic-xcc:4.2.2',
                ':metadata-extractor:2.3.1',
                ':msv:1.0',
                ':resolver:1.0',
                ':saxon:9pe',
                ':tagsoup:1.2',
                ':xep:1.0',
                ':xmlunit:1.3'
    }
}

现在这里是包含上述插件的项目的构建配置，无法使用Log4j错误执行思科库调用：

grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
grails.plugin.location.'adv-provisioning-server' = "../../../adv-provisioning-server/branches/AlamSher_AdvProvisioningServer"
grails.plugin.location.'advoss-orm-core' = "../../../advoss-orm-core-grails-plugin/branches/ShahbazORMPlugin"
//grails.plugin.location.'advoss-trouble-ticket' = "../../../advoss-trouble-ticket-grails-plugin/branches/ShahbazTroubleTicketPlugin"

//grails.project.war.file = "target/${appName}-${appVersion}.war"

grails.project.dependency.distribution = {
    remoteRepository(id: "release", url: "http://192.168.0.2:8080/artifactory/plugins-release-local") {
        authentication username: "maven_user", password: "mav3nus3r"
    }
}

grails.project.dependency.resolution = {

    pom true

    inherits("global") {
        // uncomment to disable ehcache
        // excludes 'ehcache'
    }

如果我理解正确，你就会遇到冲突的依赖。

假设使用此工件字符串从maven解析了第三方思科库："com.cisco.foo"。你可以在BuildConfig.groovy的一部分之后添加一个闭包来排除Log4J传递依赖，如下所示：

dependencies {
  // ... other dependencies
  compile("com.cisco.foo") {
    excludes "log4j"
  }
}

这将有效地排除Cisco lib包含的Log4J 1.1.3。

编辑：如果JAR只在lib/而不是上面的位，IIRC你可以这样做：

dependencies {
  // ... other dependencies
  inherits("global") {
    excludes "log4j"
  }
}

在这种情况下，同样是lib/目录中的log4j 1.1.3，或者Cisco JAR是一个带有Log4J类的胖罐。后一种情况可能会非常棘手，如果是这样，你应该向你提出这个问题。
