1. 创建 maven 项目
1.1 创建 p1 项目
创建 leffss/p1 项目，添加以下文件：
src/main/java/com/mycompany/app/App.java
package com.mycompany.app;
/**
* Hello world!
*/
public class App
{
private final String message = "Hello World!";
public App() {}
public static void main(String[] args) {
System.out.println(new App().getMessage());
}
private final String getMessage() {
return message;
}
}
src/test/java/com/mycompany/app/AppTest.java
package com.mycompany.app;
import java.io.ByteArrayOutputStream;
import java.io.PrintStream;
import org.junit.Before;
import org.junit.Test;
import org.junit.After;
import static org.junit.Assert.*;
/**
* Unit test for simple App.
*/
public class AppTest
{
private final ByteArrayOutputStream outContent = new ByteArrayOutputStream();
@Before
public void setUpStreams() {
System.setOut(new PrintStream(outContent));
}
@Test
public void testAppConstructor() {
try {
new App();
} catch (Exception e) {
fail("Construction failed.");
}
}
@Test
public void testAppMain()
{
App.main(null);
try {
assertEquals("Hello World!" + System.getProperty("line.separator"), outContent.toString());
} catch (AssertionError e) {
fail("\"message\" is not \"Hello World!\"");
}
}
@After
public void cleanUpStreams() {
System.setOut(null);
}
}

1.2 创建 p2 项目
创建 leffss/p2 项目，添加以下文件：
src/main/java/com/mycompany/app2/App.java
package com.mycompany.app2;
/**
* Hello world!
*/
public class App
{
private final String message = "Hello World!";
public App() {}
public static void main(String[] args) {
System.out.println(new App().getMessage());
}
private final String getMessage() {
return message;
}
}

public class AppTest
{

@Before
public void setUpStreams() {
System.setOut(new PrintStream(outContent));
}
@Test
public void testAppConstructor() {
try {
new App();
} catch (Exception e) {
fail("Construction failed.");
}
}
@Test
public void testAppMain()
{
App.main(null);
try {
assertEquals("Hello World!" + System.getProperty("line.separator"), outContent.toString());
} catch (AssertionError e) {
fail("\"message\" is not \"Hello World!\"");
}
}
@After
public void cleanUpStreams() {
System.setOut(null);
}
}

2. 上传到 package 仓库
在 leffss/p1 项目中操作
2.1 上传 package
项目根目录创建 maven 配置文件 ci_settings.xml：
<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">
<servers>
<server>
<id>gitlab-maven</id>
<configuration>
<httpHeaders>
<property>
<name>Job-Token</name>
<value>${CI_JOB_TOKEN}</value>
</property>
</httpHeaders>
</configuration>
</server>
</servers>
</settings>
pom.xml 新增 repositories 与 distributionManagement 配置：
...
<url>http://maven.apache.org</url>
<repositories>
<repository>
<id>gitlab-maven</id>
<url>${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/maven</url>
</repository>
</repositories>
<distributionManagement>
<repository>
<id>gitlab-maven</id>
<url>${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/maven</url>
</repository>
<snapshotRepository>
<id>gitlab-maven</id>
<url>${CI_API_V4_URL}/projects/${CI_PROJECT_ID}/packages/maven</url>
</snapshotRepository>
</distributionManagement>
<dependencies>
...
项目根目录创建新增 .gitlab-ci.yml
stages:
- deploy
deploy:
stage: deploy
image: maven:3.8.5-jdk-11
script:
- 'mvn deploy -s ci_settings.xml'
artifacts:
paths:
- target/
only:
- tags
给项目添加一个 tag 就会触发 pipeline：
打包并上传成功：
2.2 查看 package
项目 > Packages & Registries > Package Registry
-
多次上传相同版本不会覆盖，因为 gitlab 会为每次提交的 pom 和 jar 文件添加一个时间与序号
-
其中
maven-metadata.xml记录了最新的提交信息<?xml version="1.0" encoding="UTF-8"?> <metadata modelVersion="1.1.0"> <groupId>com.mycompany.app</groupId> <artifactId>my-app</artifactId> <versioning> <lastUpdated>20220609085206</lastUpdated> <snapshot> <timestamp>20220609.085206</timestamp> <buildNumber>2</buildNumber> </snapshot> <snapshotVersions> <snapshotVersion> <extension>jar</extension> <value>1.0-20220609.085206-2</value> <updated>20220609085206</updated> </snapshotVersion> <snapshotVersion> <extension>pom</extension> <value>1.0-20220609.085206-2</value> <updated>20220609085206</updated> </snapshotVersion> </snapshotVersions> </versioning> <version>1.0-SNAPSHOT</version> </metadata>
注意：上传到项目仓库时，组仓库也是可以看到并使用的
提交多版本时：
3. 使用 package
在 leffss/p2 项目中操作，方法是使用 mvn dependency:get 测试是否能够正常下载刚才上传的 maven 包。
项目根目录创建 maven 配置文件 ci_settings.xml：
<settings xmlns="http://maven.apache.org/SETTINGS/1.1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.1.0 http://maven.apache.org/xsd/settings-1.1.0.xsd">
<servers>
<server>
<id>gitlab-maven</id>
<configuration>
<httpHeaders>
<property>
<name>Job-Token</name>
<value>${CI_JOB_TOKEN}</value>
</property>
</httpHeaders>
</configuration>
</server>
</servers>
</settings>
pom.xml 新增 repositories 、 distributionManagement 与 dependency 配置：
...
<url>http://maven.apache.org</url>
<repositories>
<repository>
<id>gitlab-maven</id>
<url>http://gitlab.example.com/api/v4/projects/3/packages/maven</url>
</repository>
</repositories>
<distributionManagement>
<repository>
<id>gitlab-maven</id>
<url>http://gitlab.example.com/api/v4/projects/3/packages/maven</url>
</repository>
<snapshotRepository>
<id>gitlab-maven</id>
<url>http://gitlab.example.com/api/v4/projects/3/packages/maven</url>
</snapshotRepository>
</distributionManagement>
<dependencies>
<dependency>
<groupId>com.mycompany.app</groupId>
<artifactId>my-app</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
...
- http://gitlab.example.com/api/v4/projects/3/packages/maven 中的 3 为
leffss/p1的项目 id
项目根目录创建新增 .gitlab-ci.yml
stages:
- test
test:

对比了一下正常情况下，下载请求为：
http://gitlab.example.com/api/v4/projects/3/packages/maven/com/mycompany/app/my-app/1.0-SNAPSHOT/maven-metadata.xml
http://gitlab.example.com/api/v4/projects/3/packages/maven/com/mycompany/app/my-app/1.0-SNAPSHOT/my-app-1.0-20220609.085206-2.pom
http://gitlab.example.com/api/v4/projects/3/packages/maven/com/mycompany/app/my-app/1.0-SNAPSHOT/my-app-1.0-20220609.085206-2.jar
- 首先获取 maven-metadata.xml ，然后再从中获取到后面 pom 和 jar 的正确名称
但是使用 mirror 方式下，下载请求为：
http://gitlab.example.com/api/v4/projects/3/packages/maven/com/mycompany/app/my-app/1.0-SNAPSHOT/maven-metadata.xml
http://gitlab.example.com/api/v4/projects/3/packages/maven/com/mycompany/app/my-app/1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.pom
http://gitlab.example.com/api/v4/projects/3/packages/maven/com/mycompany/app/my-app/1.0-SNAPSHOT/my-app-1.0.jar
这样子就无法下载到 pom 与 jar 了。由于对 maven 不是太熟悉，原因未知。
解决方法三：搭建 gitlab 时开启 https（强烈建议使用有效证书）
4. 使用 api 直接上传 package
4.1 添加项目 Deploy tokens
项目 > settings > Repository > Deploy tokens，权限选择：read_package_registry、write_package_registry
4.2 api 上传 package
上传命令：
curl --request PUT \
--upload-file my-app-3.0.pom \
--header "Deploy-Token: t42PhRv6ighShpChNZSD" \
"http://gitlab.example.com/api/v4/projects/3/packages/maven/com/mycompany/app/my-app/3.0-SNAPSHOT/my-app-3.0-SNAPSHOT.pom"
curl --request PUT \
--upload-file my-app-3.0.jar \
--header "Deploy-Token: t42PhRv6ighShpChNZSD" \
"http://gitlab.example.com/api/v4/projects/3/packages/maven/com/mycompany/app/my-app/3.0-SNAPSHOT/my-app-3.0-SNAPSHOT.jar"
- 如果 token 是个人token，则将 Deploy-Token 改为 Private-Token 即可
4.3 查看 api 上传的 package
结果：
- 可以看到上传的文件名称和在 ci/cd 任务上传有区别的（未添加时间和序号），然后也没有 maven-metadata.xml 文件
4.4 测试 api 上传的 package 可用性
