异常1：
[ERROR] Failed to execute goal on project biz_zhuhai: Could not resolve dependencies for project biz_zhuhai:biz_zhuhai:jar:0.0.1-SNAPSHOT: Failed to collect dependencies for [com.maywide.ibh:lib345:pom:1.0 (compile)]: Failed to read artifact descriptor for com.maywide.ibh:lib345:pom:1.0: Could not transfer artifact com.maywide.ibh:lib345:pom:1.0 from/to releases (http://localhost:9888/nexus-2.0.3/content/repositories/releases): Connection to http://localhost:9888 refused: Connection refused: connect -> [Help 1]
解决方法：
这是配置的url有错误或者是私服没有配好，导致构件下载时出错。如果没有jar包需要在私服里下载，可以不配置私服的，也就是可以把setting.xml的profiles里的东西全部删除的。
异常2：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.10:test (default-test) on project web_nanchang: There are test failures.
[ERROR]
[ERROR] Please refer to E:\maven\web_nanchang\target\surefire-reports for the individual test results.
解决方法：
这是因为测试代码时遇到错误，它会停止编译。只需要在pom.xml的<project>里添加以下配置，使得测试出错不影响项目的编译。
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<configuration>
<testFailureIgnore>true</testFailureIgnore>
</configuration>
</plugin>
</plugins>
</build>

解决方法：
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>
