專案中需要臨時在maven中匯入一個本地的jar，開始是在maven中這樣配置的：

<dependency>
    <groupId>com.dtdream.dthink</groupId>
    <artifactId>uim-mock-sdk</artifactId>
    <version>1.1-SNAPSHOT</version>
    <scope>system</scope>
    <systemPath>D:/Driver/uim-mock-sdk-1.1-SNAPSHOT.jar</systemPath>
 
</dependency>
<dependency>
    <groupId>com.dtdream.dthink</groupId>
    <artifactId>uim-mock-utils</artifactId>
    <version>1.1-SNAPSHOT</version>
    <scope>system</scope>
    <systemPath>D:/Driver/uim-mock-utils-1.1-SNAPSHOT.jar</systemPath>
 

</dependency>

然後maven install jar,但是在編譯過程中會一直報錯ClassNotFound，找不到jar包中的某個類，此時在專案中開啟dependencies可以看到是有這個類的，初步懷疑是沒有把jar包打包到專案的war中；

於是，直接將jar包放入專案中，專案目錄下定義lib資料夾，將jar包放入該資料夾下。同時pom.xml檔案這樣配置：

<dependency>
    <groupId>com.dtdream.dthink</groupId>
    <artifactId>uim-mock-sdk</artifactId>
 
    <version>1.1-SNAPSHOT</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/lib/uim-mock-sdk-1.1-SNAPSHOT.jar</systemPath>
</dependency>
<dependency>
    <groupId>com.dtdream.dthink</groupId>
    <artifactId>uim-mock-utils</artifactId>
    <version>1.1-SNAPSHOT</version>
    <scope>system</scope>
    <systemPath>${project.basedir}/lib/uim-mock-utils-1.1-SNAPSHOT.jar</systemPath>
</dependency>

在pom.xml的maven-war-plugin中配置如下：

<resource>

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-war-plugin</artifactId>
    <configuration>
        <failOnMissingWebXml>false</failOnMissingWebXml>
        <webResources>
            <resource>
                <directory>${project.build.directory}/xxxxxx/</directory>
            </resource>
<resource>
                <directory>${project.basedir}/lib</directory>
                <targetPath>WEB-INF/lib</targetPath>
                <filtering>false</filtering>
                <includes>
                    <include>*.jar</include>
                </includes>
            </resource>        </webResources>
        <warSourceExcludes>view/master/**</warSourceExcludes>
        <packagingExcludes>**/*.map</packagingExcludes>
    </configuration>
</plugin>

後若有其他缺少的jar，在pom中引入，重新mvn打包，然後編譯執行，問題解決；
