Pay tribute to ant (Ant) (3)

Pay tribute to ants (3)

Listing 5:

Manifest-Version: 1.0created-by: Dorianmain-Class: Dorian.HelloworldFrameclass-path: panel.jar manifest-version: 1.0created-by: DorianMain-Class: Dorian.HelloWorldMainClass-path: frame.jar

How is your helloworldmain.jar run? However, a little problem is a little problem: That is helloworldmain depends on HelloWorldFrame, and HelloWorldFrame relies on HelloWorldPanel. When I tried to HelloWorldMain prior to HelloWorldFrame and HelloWorldPanel, an error will occur.

Therefore, we need a method to component files in the correct order. At this time, you can use the main side of the ANT.

Then, establish a component file build.xml in the HelloWorld home directory (Listing 6).

Listing 6:

< / Project> You can see that the primary component file is simply commissioned and ensures that the components files of the sub-project in the correct order.

Now just run Ant in the command line in the HelloWorld directory, you can make the entire project.

summary

Although it is just a simple implementation, it demonstrates how to create an application in an executable file. Also demonstrated how to package several classes shared by multiple applications in the same JAR file.

Of course, you may ask this role is not very obvious, but when you have hundreds (perhaps more than a dozen) subproject, these subprojects have built thousands of components. You will feel how happy it is using Ant components.
