在升级现有应用程序（最近升级并使用 Grails 2.2.4）时，我升级了应用程序的两个组件中使用的公共模块（称为 myApp-common）。这进展顺利，但是当我尝试升级第一个依赖模块时，我在运行“grails upgrade”命令时收到了附加的堆栈跟踪。

    WARNING: This target will upgrade an older Grails application to 2.3.0.
    Are you sure you want to continue?
               [y,n] y

| 执行 myApp-common 插件升级脚本 | 错误执行脚本时出错升级：org.codehaus.groovy.control.MultipleCompilationErrorsException：启动失败：解析期间出现一般错误：未找到四位十六进制字符代码。行：1 列：20

1 个错误（使用 --stacktrace 查看完整跟踪）

经过一番谷歌搜索，看起来这与一个已知问题有关，即在代码中包含 \u 时没有后跟十六进制代码。删除所有实例后，它仍然给出了相同的错误。接下来，我将代码当时所在的工作区从 C:\unique_workspace\Iteration21 更改为 C:\x_unique_workspace\Iteration21 以删除工作区地址中的 \u。这样做并再次尝试升级会导致此堆栈跟踪：

升级脚本似乎在更新模块所需的通用插件时阻塞了“\”字符，但我无法辨别出解决方法。

尝试执行升级（spring-security-core 插件）时我遇到了同样的问题。我在 BuildConfig.groovy 中添加了以下属性来修复它：

grails.project.work.dir = "target/work"
grails.project.plugins.dir = "${grails.project.work.dir}/plugins"

命令有问题upgrade。grails upgrade而不是手动运行更改app.grails.version=2.3.x项目目录中 application.properties 文件中的行。

这是由于/scripts/_upgrade.groovy. 它有 // 或 commonented 行，因此您可以尝试删除此文件。
