grails - 将grails-2.3.2迁移到2.4.0和将JDK 1.7迁移到1.8时出错

Question

我正在从2.3.2迁移grails-2.4.0和从1.7迁移jdk-1.8。

我正在使用this文章进行迁移。

BuildConfig.groovy

dependencies {
        // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.
        runtime 'org.springframework:spring-test:3.1.0.RELEASE'
    }

plugins {
    // plugins for the build system only
    build ":tomcat:7.0.52.1"

    // Default plugins for the compile step
    compile ":scaffolding:2.1.0"
    compile ':cache:1.1.3'

    // Persistency plugins
    runtime ":hibernate:3.6.10.14"

    // Styling plugins
    runtime ':twitter-bootstrap:3.3.4'
    runtime ":resources:1.2.14"
    runtime ":jquery:1.11.0.2"

    // PDF rendering plugins
    compile ":rendering:1.0.0"

    // Spring security plugins
    compile ":spring-security-core:2.0-RC5"

    // Uncomment these (or add new ones) to enable additional resources capabilities
    runtime ":zipped-resources:1.0.1"
    runtime ":cached-resources:1.1"
    compile ":cache-headers:1.1.7"
}

从 applicationContext.xml 中删除了 grailsResourceLoader从 web.xml 中删除了sitemesh过滤器详细信息

当我使用grails run-app运行应用程序时，它运行良好。但是当我当时使用update，Sort等时，会发生以下错误。

堆栈跟踪

我会错过升级的东西吗？还是这是我的代码中的错误？

快速帮助将不胜感激。

请在这里找到日志 log.txt。

基于stacktrace的错误是，当您命中 / wba-web / airline / index 时，您将 null 值传递给渲染函数。请复制完整的堆栈跟踪以获取更多信息。
