在Eclipse中构建现有的动态Web项目时遇到问题

Question

我正在日食中导入现有项目。我收到此错误，不知道如何解决。可能是因为JRE或JDK版本。我对此很陌生，所以我很失落。我正在寻找建议...

以下是显示的错误：

Java Build Path Problem

*Archive for required library: '.project' in project 'C***ch2' cannot be read or is not a valid ZIP file* screenshot of errors

这是类路径

。classpath

    <?xml version="1.0" encoding="UTF-8"?>
    <classpath>
    <classpathentry kind="src" path="src"/>
    <classpathentry exported="true" kind="con" path="org.eclipse.jst.server.core.container/org.eclipse.jst.server.tomcat.runtimeTarget/Apache Tomcat v7.0">

不要提出与您的第一个问题相同的第二个问题。 Having a problem in building an existing java project in eclipse

消息是说.project文件不是有效的库。它不是jar文件，也不是包含类文件的文件夹结构的目录。从项目的Java构建路径中删除该条目。
