無法運行Grails應用程序？

當我嘗試運行我的Grails應用程序，我得到了以下錯誤：無法運行Grails應用程序？

，這是我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 'com.thoughtworks.xstream:xstream:1.4.2'

     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' 
    } 
}

我認爲類是我的類路徑上，所以我不要認爲這是一個階級路徑問題。有誰知道如何解決它？

感謝，

請提供更多信息。什麼是Grails版本？這是一個新項目？你已經嘗試過'grails clean'和'grails compile'嗎？ –

grails版本是2.1.1。我將這個項目複製到另一臺機器上，它工作正常。我嘗試清理並再次運行該項目，但仍顯示相同的錯誤。 –

你可以發佈你的buildConfig嗎？ 'com.lp.labs.scconnector.GitConnector'是一些私人類嗎？我沒有找到任何關於此的信息。 –

是在lib目錄下的JAR文件com.lp.labs.scconnector.GitConnector？如果是這樣，運行grails compile --refresh-dependencies讓Grails將它添加到類路徑

是的，它位於lib文件夾中的jar文件中。我運行這個命令，沒有任何改變 –

你是從命令行還是IDE運行？爲了在STS中識別它，您需要運行Grails Tools | Refresh Dependencies來讓STS與Grails類路徑同步。 –

我從STS運行刷新依賴關係，但不起作用。 –

也許你的問題可能源於其他原因，我有同樣的錯誤，並且在各處諮詢後，我建議做一個Grails-CLEAN，一切都解決了。
