OpenShift類字符串錯誤

Question

我無法將我的spring mvc項目安裝到OpenShift。如果我推，我會得到一個錯誤remote: [ERROR] /var/lib/openshift/575b0b2b2d52719638000001/app-root/runtime/repo/src/main/java/com/controller/ReservationController.java:[73,66] error: cannot find symbo remote: [ERROR] class String

我的pom.xml。我改變了maven編譯器的源代碼和目標。

在線路73,66我已經使用命令的string.join（）;我能做些什麼來解決這個問題？我在OpenShift中使用Tomcat 7創建了應用程序。

Answer 1

String.join添加到Java8中。您使用的是Java 7 按照this教程，和

"export JAVA_HOME=/etc/alternatives/java_sdk_1.8.0" 

在

「action_hooks /啓動」 腳本。見action hooks documentation
