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

最佳答案
这是因为编译时CLASSPATH 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>
假设编译代码所需的库位于 WEB-INF/lib 下...如果它位于其他地方...输入相对于您的 build.xml 文件的该目录的路径
现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>
这就是说...在 WEB-INF/src 中编译 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)添加到类路径
可以使用多个标签来指定多个类路径
