異常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]

解決方法：

這是配置的url有錯誤或者是私服沒有配好，導致構件下載時出錯。如果沒有jar包需要在私服裏下載，可以不配置私服的，也就是可以把setting.xml的profiles裏的東西全部刪除的。

異常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.

解決方法：

這是因為測試代碼時遇到錯誤，它會停止編譯。只需要在pom.xml的<project>裏添加以下配置，使得測試出錯不影響項目的編譯。

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-surefire-plugin</artifactId>
            <configuration>
                <testFailureIgnore>true</testFailureIgnore>
            </configuration>
        </plugin>
    </plugins>
</build>

解決方法：

自己下載“apache-tomcat-6.0.29.zip”，將下載好的文件拷貝到指定文件夾“C:\Documents and Settings\Administrator\Local Settings\Temp\cargo\installs”下。

異常4：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-war-plugin:2.1.1:war (default-war) on project web_nanchang: Error assembling WAR: webxml attribute is required (or pre-existing WEB-INF/web.xml if executing in update mode) -> [Help 1]

解決方法：

maven的web項目默認的webroot是在src\main\webapp。如果在此目錄下找不到web.xml就拋出以上的異常。解決方法在pom.xml加入以下的配置。紅色字體改成你網站的根目錄。

<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>
