这让我有点不爽
做所有用户都需要做的事,应该是一个直截了当的、老练的程序,只是一个直截了当的程序。
I made the Java class I want to add to all new Java projects into a JAR file. And I got it into the JRE folder using Window > Prefs > Java > Installed JREs, etc. But come runtime, the Java interpreter just doesn t see this class as attached to my projects.
有谁知道这个傻瓜是怎么修好的吗?
我使用日圆3.6.2太阳和JRE7。
JRE并非真正打算以这种方式扩展。 如果您必须将共享的图书馆存储在 JRE 中, 应该使用 < code> ext 文件夹, 而不是顶级 JRE 文件夹 。 但是, 即使这通常也是一种不良的做法 : < a href=" https://stackoverflow.com/ questions/20689661/is- putting- ext-jars- in- the-java- home-lib-ext- directory- a- bad-ting > 是否在 JAVA_HOME/lib/ext目录中放外罐是坏事? < / a > 。
要在您的 Eclipse 工程中添加依赖性, 请使用项目 s 构建路径。 要在运行时添加依赖性, 请使用 Java 类路径 。
我会创建一个用户图书馆, 并在项目设置中添加lib。 http://goo. gl/pEoto
考虑使用马文管理您的依赖关系 。
