 错误1:An error has occurred when creating this preference page

解决办法:
将环境变量Path中%JAVA_HOME%\bin;置于path最前面解决问题

    解决:maven的web项目默认的webroot是在src\main\webapp。如果在此目录下找不到web.xml就抛出以上的异常。解决方法在pom.xml加入以下的配置。红色背景字体改成你网站的根目录。


< build > 
< finalName >simple-webapp</ finalName > 
< plugins > 
< plugin > 
< groupId >org.apache.maven.plugins</ groupId > 
< artifactId >maven-war-plugin</ artifactId > 
< version >2.1.1</ version > 
< configuration > 
< webResources > 
< resource > 
<!-- this is relative to the pom.xml directory -->
< directory >WebContent</ directory > 
</ resource > 
</ webResources > 
</ configuration > 
</ plugin > 
</ plugins > 
</ build >



 

 记录3:dependency引用本地jar包

< dependency >
< groupId >org.apache</ groupId >
< artifactId >test</ artifactId >
< version >1.0</ version >
< scope >system</ scope >
< systemPath >${basedir}/src/main/webapp/WEB-INF/lib/paypal_base.jar</ systemPath >
</ dependency >



maven使用module开发生成web工程,不打war包方法
