Getting Error "Package doesn't exists" while compiling ant build.xml
提问by Swati Jha
I am new to ANT build and getting error "package org.testng.annotations does not exist" and "package org.openqa.selenium does not exist" on compiling ant build.xml.
我是 ANT 构建的新手，在编译 ant build.xml 时收到错误“包 org.testng.annotations 不存在”和“包 org.openqa.selenium 不存在”。
Here is build.xml
这是 build.xml

I have also set the JAVA_HOME C:\Program Files\Java\jdk1.7.0_25\bin and ANT_HOME C:\Users\Documents\selenium-2.35.0\apache-ant-1.9.2
我还设置了 JAVA_HOME C:\Program Files\Java\jdk1.7.0_25\bin 和 ANT_HOME C:\Users\Documents\selenium-2.35.0\apache-ant-1.9.2
Can anyone tell me how to get rid of this error.
谁能告诉我如何摆脱这个错误。

I believe the problem is here:
我相信问题出在这里：
<pathconvert pathsep="."
property="test.classpath"
refid="classpath_jars"/>
I'm not aware of any environment where "."is a valid path separator. The result is that ${test.classpath}is not a valid path. That is why your TestNG and Selenium classes are not accessible by the compiler.
我不知道有任何"."有效路径分隔符的环境。结果是这${test.classpath}不是一个有效的路径。这就是编译器无法访问您的 TestNG 和 Selenium 类的原因。
You might as well make test.classpathidentical to classpath_jars.
您也可以test.classpath将classpath_jars.
(I would have spotted this much sooner if your XML were properly indented.)
（如果您的 XML 正确缩进，我会更早地发现这一点。）
