This topic describes how to migrate artifacts in batches from an existing Maven private repository to an Alibaba Cloud DevOps Maven private repository.
Procedure
Packages supports two methods to migrate artifacts in batches from a Maven private repository to a Packages Maven private repository. You can make a selection based on your requirements.
Upload local files in batches
Import artifacts from Nexus3
Step 1: Download the migration tool
Download URL: https://agent-install-beijing.oss-cn-beijing.aliyuncs.com/maven-migration-jar-with-dependencies.jar
Download the JAR file from the preceding URL to your local machine and save the file as maven-migration-jar-with-dependencies.jar.
Step 2: Run the migration tool
Upload local files in batches
Make sure that Java 8 or later is installed on your machine. To view the help information, run the following command in the directory of the current JAR file: java -jar maven-migration-jar-with-dependencies.jar migrate --help.
java -jar ./target/maven-migration-jar-with-dependencies.jar migrate --help
Usage: migrate migrate [-hV] [--dryrun] [--exclude=<exclude>]
[--include=<include>] --source-dir=<sourceDir>
--target-repo-password=<repoPassword>
--target-repo-url=<repoUrl>
--target-repo-username=<repoUsername>
Migrate artifacts
--dryrun Dry run, artifacts are not uploaded.
--exclude=<exclude> Exclude groupIds and multiple groupIds separated by commas.
-h, --help Show this help message and exit.
--include=<include> Include groupIds and multiple groupIds separated by commas.
--source-dir=<sourceDir>
The source directory, such as ~/.m2/repository.
--target-repo-password=<repoPassword>
The password to access the destination repository can be found in the guide of the repository on packages.aliyun.com.
--target-repo-url=<repoUrl>
The destination repository address can be found in the repository guide on packages.aliyun.com.
--target-repo-username=<repoUsername>
The username to access the destination repository can be found in the repository guide on packages.aliyun.com.
-V, --version Print version information and exit.
If you find garbled Chinese characters in the help information, run the chcp 65001 command in the command line and run the Java command.
Example:
java -jar maven-migration-jar-with-dependencies.jar migrate --source-dir="/root/.m2/repository" --target-repo-url="https://packages.aliyun.com/xxxxxx/maven/xxxxx-release-ogcezj" --target-repo-username="672aca1cbecc93xxxxx" --target-repo-password="xxxxxxx" --include="com.taobao.text" --exclude="junit"You can upload all artifacts with the com.taobao.text groupId to the maven-releases Nexus repository by running the preceding command. To view the information about the specific parameters, perform the following steps. Go to the repository details page. In the left-side navigation pane, click User Guide. On the page that appears, click Local files batch upload.

Make sure that Java 8 or later is installed on your machine. To view the help information, run the following command in the directory of the current JAR package: java -jar maven-migration-jar-with-dependencies.jar migrateNexus --help.
java -jar maven-migration-jar-with-dependencies.jar migrateNexus --help
Usage: migrate migrateNexus [-hV] [--dryrun] [--exclude=<exclude>]
[--include=<include>] --nexus-host=<nexusHost>
--source-repo-id=<repoId>
--source-repo-password=<repoPassword>
--source-repo-username=<repoUsername>
--target-repo-password=<repoPassword>
--target-repo-url=<repoUrl>
--target-repo-username=<repoUsername>
Migrate Nexus3 artifacts
--dryrun Dry run, artifacts are not actually uploaded.
--exclude=<exclude> Exclude groupIds and multiple groupIds separated by commas.
-h, --help Show this help message and exit.
--include=<include> Include groupIds and multiple groupIds separated by commas.

--source-repo-id=<repoId> The source repository ID
--source-repo-password=<repoPassword> The password to access the source repository
--source-repo-username=<repoUsername> The username to access the source repository
--target-repo-password=<repoPassword> The password to access the destination repository can be found in the repository guide on packages.aliyun.com
--target-repo-url=<repoUrl> The destination repository URL can be found in the repository guide on packages.aliyun.com
--target-repo-username=<repoUsername> The username to access the destination repository can be found in the repository guide on packages.aliyun.com
-V, --version Print version information and exit.If you find garbled Chinese characters in the help information, run the chcp 65001 command in the command line and run the Java command.
Example:
java -jar maven-migration-jar-with-dependencies.jar migrateNexus --source-repo-id="maven-releases" --source-repo-username="admin" --source-repo-password="admin123" --nexus-host="http://localhost:8081" --target-repo-url="https://packages.aliyun.com/xxxxxxxx/maven/xxxxx-release-ogcezj" --target-repo-username="672aca1cbecc93xxxxx" --target-repo-password="gKUf3xxxxx(" --include="com.taobao.text"You can upload all artifacts with the com.taobao.text groupId to the maven-releases Nexus repository by running the preceding command. To view specific parameter information, perform the following steps. Go to the repository details page. In the left-side navigation pane, click User Guide. On the page that appears, click Import from Nexus3.
Step 3: View the execution results
