Spock 错误：找不到共享实例字段

Question

我刚刚克隆了示例项目 geb-grails-example 并遇到了与 Spock 相关的错误。

运行 grails (2.0.3) 命令test-app 时，出现以下错误：

| Server running. Browse to http://localhost:8080/geb-example-grails
| Server stopped
| Tests PASSED - view reports in target\test-reports
| Error Error running script test-app --stacktrace: cannot find shared instance field (NOTE:         Stack trace has been filtered. Use --verbose to see entire trace.)

任何帮助或指针将不胜感激，

提前致谢

注意事项：

我正在使用

Geb 版本是 0.7，Spock 版本是 0.6

Answer 1

我遇到了同样的问题（使用 Geb 0.7.0、Spock 0.6、Grails 2.0.3 和 Groovy 1.8.6）。我发现的一种解决方法是将规范更改为从 GebSpec 而不是 GebReportingSpec 扩展。测试在此更改后通过 - 但我不知道这会产生什么长期影响（我对这个堆栈很陌生）。

Answer 2

尝试使用 -noreloading 标志运行测试：

grails -noreloading 测试应用

Answer 3

我在我的新系统上重新克隆了 repo，所有测试都通过了。我不知道上一个错误的原因。结束问题。

Answer 4

grails clean
grails compile
grails package

帮我解决了这个问题
