使用Eclipse编译java 7 for java 6 [英] Compiling java 7 for java 6 with Eclipse

问题描述

我需要编译一个Java 6项目以使用Java 6或7（我无法升级我生活中的所有计算机）。我一直在搜索，发现有点有用的 东西，但我比较新的java - 我不了解如何使用所提供的替代方案（ant-build，Maven，javac）。

我的程序不使用Java 6中不可用的任何API方法，但它确实使用另一个外部的.JAR的API（它是一个示例程序的基本插件）

有没有一个简单的方法来做到这一点与Eclipse的导出功能，或者我需要使用其他程序/方法吗？

如果我需要使用除Eclipse之外的其他东西，我最好如何做一个多类，多包文件依赖于另一个外部的.jar的API？

解决方案

右键单击eclipse中的项目并打开项目属性。

然后导航到 Java编译器，并将合规级别设置为1.6。

应该这样做。

I need to compile a project for Java 6 to use with java 6 or 7 (I can't upgrade all of the computers in my life). I've been searching all over and found somewhat helpful stuff, but I'm rather new to java - I don't understand much of how to use the presented alternatives (ant-build, Maven, javac).

My program does not use any API methods that are not available in Java 6, but it does use the API of another external .JAR (it is a basic plugin for an example program)

Is there a simple way to do this with Eclipse's Export function, or do I need to use some other program/method?

If I need to use something other than Eclipse, how would I best go about doing it for a multi-class, multi-package file dependent on another external .jar's API?

解决方案

Right-click on your project in eclipse and open the project properties.

Then navigate to Java compiler and set the compliance level to 1.6.

That should do it.
