1. 在 pom.xml 文件中添加如下所示的本地仓库配置：
<repositories>
    <repository>
        <id>my-local-repo</id>
        <url>file://${project.basedir}/repository</url>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
            <checksumPolicy>ignore</checksumPolicy>
        </snapshots>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
            <checksumPolicy>ignore</checksumPolicy>
        </releases>
    </repository>
    <repository>
        <id>central</id>
        <url>https://repo.maven.apache.org/maven2</url>
        <snapshots>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
            <checksumPolicy>ignore</checksumPolicy>
        </snapshots>
        <releases>
            <enabled>true</enabled>
            <updatePolicy>never</updatePolicy>
            <checksumPolicy>ignore</checksumPolicy>
        </releases>
    </repository>
</repositories>
2. 在 pom.xml 文件中添加如下所示的 maven 插件配置，注意使用指定的版本。
<build>
    <plugins>
        <plugin>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.1</version>
            <configuration>
                <source>${java.version}</source>
                <target>${java.version}</target>
            </configuration>
        </plugin>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>3.1.0</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <descriptorRefs>
                            <descriptorRef>jar-with-dependencies</descriptorRef>
                        </descriptorRefs>
                        <finalName>chaincode</finalName>
                        <transformers>
                            <transformer
                                    implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>chaincode.example.SimpleChaincode</mainClass>
                            </transformer>
                        </transformers>
                        <filters>
                            <filter>
                                <!-- filter out signature files from signed dependencies, else repackaging
                                    fails with security ex -->
                                <artifact>*:*</artifact>
                                <excludes>
                                    <exclude>META-INF/*.SF</exclude>
                                    <exclude>META-INF/*.DSA</exclude>
                                    <exclude>META-INF/*.RSA</exclude>
                                </excludes>
                            </filter>
                        </filters>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>
3. 在 pom.xml 中添加相关依赖，示例如下：
<dependencies>
    <dependency>
        <groupId>org.hyperledger.fabric-chaincode-java</groupId>
        <artifactId>fabric-chaincode-protos</artifactId>
        <version>2.3.1</version>
    </dependency>
    <dependency>
        <groupId>org.hyperledger.fabric-chaincode-java</groupId>
        <artifactId>fabric-chaincode-shim</artifactId>
        <version>2.3.1</version>
        <exclusions>
            <exclusion>
                <groupId>com.github.everit-org.json-schema</groupId>
                <artifactId>org.everit.json.schema</artifactId>
            </exclusion>
        </exclusions>
    </dependency>
    <dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
        <version>1.18.16</version>
    </dependency>
</dependencies>
4. 使用如下命令将合约依赖下载到 repository 目录中。
  mvn dependency:copy-dependencies -DoutputDirectory=repository -Dmdep.useRepositoryLayout=True -Dmdep.copyPom=True
5. 在合约根目录中使用zip -r xxx.zip *命令将合约进行打包。
