尽管设置为 1.7，但 IntelliJ IDEA 13 仍使用 Java 1.5 [英] IntelliJ IDEA 13 uses Java 1.5 despite setting to 1.7

问题描述

尽管在所有项目设置中(包括在File -> Project Structure -> Project :: Project SDK)中指定了JDK 1.7，但IntelliJ 13 会产生以下错误code> 尝试编译一些使用菱形运算符的简单 Java 7 代码时:

Despite specifying JDK 1.7 in all project settings (including in File -> Project Structure -> Project :: Project SDK), the following error is produced by IntelliJ 13 when trying to compile some simple Java 7 code which does use the diamond operator:

java: diamond operator is not supported in -source 1.5
(use -source 7 or higher to enable diamond operator)

配置中是否还有其他地方应该启用预期的 -source 7 选项?

Is there any other place in the configuration where the expected -source 7 option should be enabled?

推荐答案

如果这些都没有帮助(我的情况)，您可以在 pom.xml 中进行设置，如下所示:

If nothing of this helps (my case), you can set it in your pom.xml, like this:

<properties>
  <maven.compiler.source>1.7</maven.compiler.source>
  <maven.compiler.target>1.7</maven.compiler.target>
</properties>
