Adding JAR to CLASSPATH in Mac OS
提问by Tiago Veloso
I am trying to set up the CLASSPATH for Java under Mac OS.
我正在尝试在 Mac OS 下为 Java 设置 CLASSPATH。
Specifically I am trying to add a couple of JAR archives to it.
具体来说，我正在尝试向其中添加几个 JAR 档案。
If I do it like:
如果我这样做：
## Setting up ASM bytecode instructor library
export CLASSPATH=$CLASSPATH:/Users/fork/Dev/ASM/lib/all/asm-all-3.3.1.jar
It works fine. However, if I set it like the documentation recommends:
它工作正常。但是，如果我按照文档建议的方式设置它：
## Setting up ASM bytecode instructor library
export CLASSPATH=$CLASSPATH:/Users/fork/Dev/ASM/lib/all/*
It does not seem to work.
它似乎不起作用。
The thing is that I want to add, let's say 10 jars, it sounds impractical to add one-by-one.
问题是我想加，比如说10罐，一一加听起来不切实际。
Is there a solution?
有解决办法吗？

You must set the jars on the classpath individually. There are ways around this though. One that I use is starting the java app with a shell script that contains something like this:
您必须单独在类路径上设置 jar。有办法解决这个问题。我使用的一个是使用包含以下内容的 shell 脚本启动 java 应用程序：
cd $JAR_DIR
jars=($(ls *.jar))
JAR_PATH=""
dir=$(pwd)
for i in "${jars[@]}"; do
JAR_PATH="${JAR_PATH}:$dir/$i"
done
CLASSPATH=$CLASSPATH:$JAR_PATH
This will work.
这将起作用。
