Question

我获得了一个脚本来编译源代码并将它们部署到Tomcat webserver。

如果我在Eclipse中编译源代码，它们就可以正常编译。

但是使用脚本我得到以下输出：

Buildfile: C:\Dev\workworkspace\myapp\build.xml
     [echo] website root dir is C:/Dev/ServerXamp/tomcat/myapp/myapp line sepa
rator is

clean-build:

这是因为编译CLASSPATH时不正确。您可以通过执行以下操作来缓解此问题：

添加这样的属性

<path id="compile.classpath">
    <fileset dir="WEB-INF/lib">
        <include name="*.jar" />
    </fileset>
</path>

假设您需要编译代码的库位于WEB-INF / lib下...如果它位于其他位置...输入相对于build.xml文件的该目录的路径

现在编译时请执行以下操作：

<target name="compile" depends="copyfiles">
    <javac destdir="WEB-INF/classes" debug="true" srcdir="WEB-INF/src" includeantruntime="false">
        <classpath refid="compile.classpath" />
    </javac>
</target>

这就是说...编译WEB-INF / src中的java代码并将类文件放在WEB-INF / classes中......并将WEB-INF / lib（通过compile.classpath引用）添加到CLASSPATH

您可以使用多个标签来指定多个类路径
