How to set ANT_HOME with Windows?

问题:

How can I easily set ANT_HOME under Windows? I added "D:\Installz\apache-ant-1.8.2\bin;" to my system environment variable PATH and I also created an ANT_HOME variable.

回答1:

I expect you to be running on Windows (since you are using %). Simply add a new environment variable (Right-click on My Computer > Properties > Advanced > environment Variable) or using SET ANT_HOME=<path> using command line (in that cas, it will only be active on that command line).

Once set you should be able to verify its value by doing echo %ANT_HOME% in command line

The % sign around the variable indicates it is an environment variable.

For linux use the export ANT_HOME=<path> in command line or in your ~/.profile (persistent, require logout/login). Use echo $ANT_HOME for verification.

In Windows 7 you can go to Control Panel\All Control Panel Items\System or right click on Computer and then to “Advance system setting”

1. Choose Advanced Tab
2. Click "Environment Variables" button
3. In System Variables, click "New" button
4. Set Variable Name: ANT_HOME and value as {directoryPath}\apache-ant-1.8.2 (Ex: D:\Installz\apache-ant-1.8.2)
5. Click OK

6. Either click again on New button if you do not have ‘Path’ Variable in there

   OR

   Select it and edit by adding the value : %ANT_HOME%\bin;

7. Click OK
8. To check if ANT is properly configured - In command prompt, type ant -version
9. It should give the ant version installed on your machine

ANT_HOME is the path to your ant installation dir, in your case "D:\Installz\apache-ant-1.8.2" and JAVA_HOME is java install dir e.g. "C:\Program Files\Java\jdk1.7.0", that's on my machine

On Windows, %% (percent) symbols are used to signify variables.

so to set both variables you can do either

in command prompt, only valid for the session of the particular command propmt

SET ANT_HOME=D:\Installz\apache-ant-1.8.2
SET JAVA_HOME="C:\Program Files\Java\jdk1.7.0"

or go to System Properties -> Advanced -> Environment Variables and set to new variables

I had a similar problem of installing JAVA JDK & ANT.

I tried installing JDK this way.

Oracle site --> download JDK setup --> double click on the set up file (on your desktop) --> accept all defaults --> finish.

we need to set environment variable in the deployment system. mycomputer (right click) --> properties --> advanced settings --> Environment variable --> system variable --> add new --> variable name: JAVA_HOME, Variable path: installation path of jdk on you computer --> click ok, ok.

To check the successful installation of Java . windows + R --> cmd --> Java -Version you would see the response as below

C:\Users\PRAX>java -version java version "1.6.0_38" Java(TM) SE Runtime Environment (build 1.6.0_38-b05) Java HotSpot(TM) 64-Bit Server VM (build 20.13-b02, mixed mode)

This shows that you have successfully installed JDK & set an environment variable too.

ANT installation:

download ant file from http://ant.apache.org/bindownload.cgi choose a mirror & download the zip (zip is the easiest method to set)

unzip the file on your computer --> copy the path (traverse till bin folder).

Now, we need to set an environment variable, Cmd --> set ANT_HOME = installation path --> press Enter if you have correctly entered, it wont throw any error. now execute, echo %ANT_HOME% you would see the result as your installation path.

your work is done.

you can check the environment variable even in computer properties by default after executing the above set up.

Hope, its useful.

A more flexible solution is to do all that 'environment stuff' in a batch file that starts your ant script, works also when there are no rights to change the environment variables.
