鉴于已安装NetBeans，如何从命令行（在Windows上）使用ant？

Question

I have NetBeans 8.0.2 installed on my Windows 7 (64-bit) machine. I have also the JDK installed (Java SE Development Kit 8 update 66 (64-bit)).

I want to run ant from the command line, but the closest I think I've come to getting it to run is the following:

java -jar "C:\Program Files\NetBeans 8.0.2\extide\ant\lib\ant.jar"

but I got the error

Error: Could not find or load main class org.apache.tools.ant.Main

I also tried the following, thinking that Main.class might be inside ant.jar , but got the same error:

java -cp "C:\Program Files\NetBeans 8.0.2\extide\ant\lib\ant.jar" -jar "C:\Program Files\NetBeans 8.0.2\extide\ant\lib\ant.jar"

I've spent at least an hour searching online and StackOverflow for the anser. The closest I've found is Compile NetBeans project from command line by using Ant , but it assumes that ant is accessible from the command line already.

To set up ant to work from the command line

1. Add C:\\Program Files\\NetBeans 8.0.2\\extide\\ant\\bin to your PATH
2. Add the environment variable JAVA_HOME with the value C:\\Program Files\\Java\\jdk1.8.0_66 (adjust this if you end up using a different version, of course).

Now that it is set up, simply use ant from the command line normally.

To rebuild the project, for example, simply do the following:

1. Open a new command prompt
2. Go to the project directory
3. Type ant clean jar
