我得到了一个脚本来编译源代码并将它们部署到 Tomcat 网络服务器。

如果我在 Eclipse 中编译源代码，它们编译得很好。

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:

这是因为在编译 CLASSPATH 时不正确。您可以通过执行以下操作来缓解这种情况：

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...输入该目录相对于您的 build.xml 文件的路径

现在在编译时执行以下操作：

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

也就是说...编译 WEB-INF/src 中的 java 代码并将类文件放入 WEB-INF/classes ...并将 WEB-INF/lib（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
