java - Eclipse Design Tab 检测到错误的 Java

Question

当我单击“设计”选项卡时，出现此错误:

Incompatible Java Versions

Eclipse is running under 1.7, but this Java project has a 1.8 Java compliance level, so WindowBuilder will not be able to load classes from this project. Use a lower level of Java for the project, or run Eclipse using a newer Java version. 

我已经检查了 window> 首选项:

1. >java>编译器设置为 1.8
2. >java>安装的 JRE 默认为 1.8 JDK

我错过了什么吗？

Answer 1

looks like JAVA_HOME is set to the java 7 one, will this require a restart?

您实际上是使用 Java 7 执行 eclipse，您可以更新 JAVA_HOME 以指向 Java 8，然后重新启动 eclipse(而不是您的计算机)。
