安装外部java包 [英] Installing an external java package

问题描述

我是java的新手，我正在尝试构建一个具有外部依赖关系的项目。当我尝试构建它时

I am new to java, and I am trying to build a project that has an external dependency. When I try to build it

[javac] Compiling 814 source files to ~/Desktop/Dev/bitcoinj/out
[javac] ~/Desktop/Dev/bitcoinj/src/com/google/bitcoin/core/Block.java:25: package org.slf4j does not exist
[javac] import org.slf4j.Logger;
[javac] ...

如何安装缺少的外部包？是否有类似于python的java包管理器 pip ？

How can install the missing external package? Is there a java package manager similar to the python pip?

推荐答案

我不知道包管理器。您将不得不手动下载jar文件 - 在本例中，它来自 http：//www.slf4j。组织/ 。之后，您可以像Dennis所说的那样，或者将jar文件显式添加到类路径中。

There's not a package manager that I know of. You're going to have to manually download the jar file -- in this case, its from http://www.slf4j.org/ . After that, you can either do as Dennis says, or add the jar file explicitly to your classpath.
