我想使用Groovy DSL配置Logback。該文件非常簡單:無法使用logback.groovy,但logback.xml工作
import ch.qos.logback.classic.encoder.PatternLayoutEncoder
import ch.qos.logback.core.ConsoleAppender
import static ch.qos.logback.classic.Level.DEBUG
import static ch.qos.logback.classic.Level.INFO
appender("stdout", ConsoleAppender) {
encoder(PatternLayoutEncoder) {
pattern = "%d %p [%c] - <%m>%n"
}
}
root(INFO, ["stdout"])
我使用Gradle構建我的應用程序並使用jettyRun運行它。我得到以下錯誤:
Failed to instantiate [ch.qos.logback.classic.LoggerContext]
Reported exception:

但是,當我切換到等效的XML配置,一切正常。我究竟做錯了什麼?
使用Logback 1.0.0。試用Logback 1.0.3。
好的,我將創建一個示例項目。我使用Groovy 1.8.6。 – Infeligo
太好了。期待錯誤報告。 – Ceki
