IntelliJ compile for Java 7 JRE using Java 8 SDK
提问by arik
I have the Java 8 SDK and runtime, and a project that is only using Java 7 features. I was wondering whether I could set up intellij to build a Java-7-level jar, something that is definitely possible from command line?
我有 Java 8 SDK 和运行时，以及一个仅使用 Java 7 功能的项目。我想知道我是否可以设置 intellij 来构建 Java-7 级别的 jar，这绝对可以从命令行实现？
So far, I have tried simply setting the project language level to 7 as an experiment, but that is obviously insufficient and not really what I need.
到目前为止，我已经尝试简单地将项目语言级别设置为 7 作为实验，但这显然是不够的，也不是我真正需要的。
I have also seen this question on SO: "Intellij IDEA using java7 compiler to compile when I have configured it to use Java6", but my project SDK is already set up to the newest Java version, and I merely need a Java-7-compatible artifact/jar compilation.
我也在 SO 上看到过这个问题：“ Intellij IDEA using java7 compiler to compile when I have configure it to use Java6”，但我的项目 SDK 已经设置为最新的 Java 版本，我只需要一个 Java-7-兼容的工件/jar 编译。
EDIT: I only have Java 6 and Java 8 JREs/SDKs on my local system because unfortunately Java 7 has issues on my system and is not compatible.
编辑：我的本地系统上只有 Java 6 和 Java 8 JRE/SDK，因为不幸的是 Java 7 在我的系统上有问题并且不兼容。
