ANT里面什么也没跑<target>

Question

When i put any thing inside a target tag its doesn't run whats inside it. eg.

<project name="Test" >
    <target name="clean">
        <delete dir="bin" />
        <mkdir dir="bin" />
        <echo>Hello 1</echo>
    </target>

    <target name="compile" depends="clean">
        <javac srcdir="src" destdir="bin" />
        <echo>Hello 2</echo>
    </target>

    <echo>Hello 3</echo>
</project>

All i get is:

[echo] Hello 3

Answer 1

You could either set a default task like

<project name="Test" default="compile"> 

or invoke a task from command lie (or IDE)

ant compile

Answer 2

Well no wonder since your project has no default = "" attribute specified.

You will either have to write the project element like this :

<project name="Test" default="compile">

Or you will have to call the ant.bat or whatever it is you are calling with the specified target to run.
