我正在使用' ant'命令在包含build.xml的目录中,但我在使用import语句时遇到错误。当它到达这一行时,
<!-- compile.gui -->
<target name="compile.gui" depends="test.properties,compile.api">
<javac srcdir="${src}" destdir="${build.classes}"
classpathref="gui.class.path" debug="on" target="1.8" includeantruntime="false">
<include name="eu/lt4el/gui/**" />
</javac>
</target>
它引用了一个java文件
package eu.lt4el.gui;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
import eu.lt4el.common.DocumentStatus;
import eu.lt4el.AppInterface;
import eu.lt4el.defcontext.Definition;
import org.apache.log4j.Logger;
public class LTStartPage extends HttpServlet
{ . . . .
我尝试编译java文件时遇到以下错误:
compile.gui:

我安装了Tomcat和JRE 8,并且我正在运行Ubuntu但是构建失败了。我不知道为什么我有错误。 感谢
编辑* 类路径在build.xml文件中定义如下:
<!-- class path for gui -->
<path id="gui.class.path">
<pathelement path="${env.CATALINA_HOME}/common/lib/servlet-api.jar"/>
<pathelement path="${lib}/log4j-1.2.14.jar"/>
</path>
答案 0 :(得分:1)
跑步:
$ export CATALINA_HOME=/opt/tomcat
$ ant
答案 1 :(得分:0)
需要根据我的安装参数设置类路径。 那是:
<!-- class path for gui -->
<path id="gui.class.path">
<pathelement path="${env.CATALINA_HOME}/common/lib/servlet-api.jar"/>
<pathelement path="${lib}/log4j-1.2.14.jar"/>
</path>
我对Tomcat的安装没有/common
。所以改成它:
<!-- class path for gui -->
<path id="gui.class.path">
<pathelement path="${env.CATALINA_HOME}/lib/servlet-api.jar"/>
<pathelement path="${lib}/log4j-1.2.14.jar"/>
</path>
修复了问题。
