Jasper Grails插件升級到Java8失敗

Question

我想將grails服務器升級為使用Java 8而不是7。升級時，遇到如下所示的異常。 其他報告了類似錯誤的人則表示，可以通過更改IDE的Java版本來解決此問題，但這似乎並不適用於此，因為如果從命令行或Intellij運行grails，則會出現異常。 其他人報告說升級tomcat會有所幫助，所以我是最新版本7。

我的Java主目錄設置為Java 8，已將編譯器的源/目標更改為1.8，以確保沒有任何潛入。我清除了所有.class文件，refresh-dependencies，clean-all，rm。 slcache等，似乎沒有任何影響。

BuildConfig.groovy:        compile ":jasper:1.11.0"
BuildConfig.groovy:        build ":tomcat:7.0.70"
BuildConfig.groovy:grails.project.target.level = 1.8
BuildConfig.groovy:grails.project.source.level = 1.8

注意，此插件使用Jasperreports 5.6.1。 我一直無法從TIBCO的網站上確定他們的.jars是否應該支持Java8。此外，我正在使用grails 2.5.5，並且在OSX上。

Answer 1

即使我看到其他人發布了可以使用更新版本的Tomcat 7的功能，但似乎更新到Tomcat 8還是對我有用。

BuildConfig.groovy:        build ":tomcat:8.0.33"

在嘗試tomcat 7.0.70之前，我一直在嘗試tomcat 7.0.55。 如果tomcat 7.0.70應該可以工作而7.0.55則不能，那么問題可能出在7.0.70撿起了一些舊的7.0.55 jar。
