当我尝试运行我的grails应用程序时出现以下错误：

这是我的build.config文件：

grails.servlet.version = "2.5" // Change depending on target container compliance (2.5 or 3.0)
grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
grails.project.target.level = 1.6
grails.project.source.level = 1.6
//grails.project.war.file = "target/${appName}-${appVersion}.war"

grails.project.dependency.resolution = {
    // inherit Grails' default dependencies
    inherits("global") {
        // specify dependency exclusions here; for example, uncomment this to disable ehcache:
        // excludes 'ehcache'
    }
    log "warn" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
    checksums true // Whether to verify checksums on resolve

    repositories {
        inherits true // Whether to inherit repository definitions from plugins

        grailsPlugins()
        grailsHome()
        grailsCentral()

        mavenLocal()
        mavenCentral()

        // uncomment these (or add new ones) to enable remote dependency resolution from public Maven repositories
        //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 {
        // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes eg.

        // runtime 'mysql:mysql-connector-java:5.1.20'
        compile 'org.eclipse.jgit:org.eclipse.jgit:2.0.0.201206130900-r'
        compile 'SC-Connector:SC-Connector:1.0'
        compile 'AccountConnector:AccountConnector:1.0'


        // runtime
        runtime 'org.springframework.ws:spring-xml:2.0.4.RELEASE'
        runtime 'org.springframework.ws:spring-ws-core:2.0.4.RELEASE'

        runtime 'org.springframework.ws:spring-oxm-tiger:1.5.10'
        runtime 'com.sun.xml.bind:jaxb-impl:2.1.12'
        runtime 'javax.xml.bind:jaxb-api:2.1'
        runtime 'com.google.guava:guava:13.0.1'
        runtime 'xmlpull:xmlpull:1.1.3.1'

    }

    plugins {
        runtime ":hibernate:$grailsVersion"
        runtime ":jquery:1.7.2"
        runtime ":resources:1.1.6"

        build ":tomcat:$grailsVersion"

        runtime ":database-migration:1.1"

        compile ':cache:1.0.0'
    }
}

我认为这些类在我的类路径上，所以我不认为它是类路径问题。有人知道如何解决它吗？

谢谢，

lib目录中的jar文件中是com.lp.labs.scconnector.GitConnector吗？如果是这样，请运行grails compile --refresh-dependencies以使Grails将其添加到类路径

答案 1 :(得分：1)

也许你的问题可能源于其他原因，我有同样的错误，经过咨询到处后我建议制作一个Grails-CLEAN，一切都解决了。

答案 2 :(得分：0)

使用命令

grails clean-all

在使用之后：

grails refresh-dependencies
grails-compile

比使用

grails run-app
