原來的：
我的目標是使用端到端的 maven 存盤庫部署和依賴項匯入。
我正在將一個 maven 專案（專案名稱 my-app）工件部署到 jFrog，然后將該工件作為依賴項添加到另一個 maven 專案（專案名稱是 my-second-app）
- 我已經設定了 jFrog 帳戶
- 使用
~/.m2/jFrog 憑據（用戶名和密碼）初始化檔案夾下的 settings.xml 并指定發布和快照的 URL - 我在專案 my-app 中添加了以下插件：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<executions>
<execution>
<id>make-a-jar</id>
<phase>compile</phase>
<goals>
<goal>jar</goal>
</goals>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<executions>
<execution>
<phase>install</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<packaging>jar</packaging>
<artifactId>${project.artifactId}</artifactId>
<groupId>${project.groupId}</groupId>
<version>${project.version}</version>
<file>
${project.build.directory}/${project.artifactId}-${project.version}.jar
</file>
</configuration>
</execution>
</executions>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-deploy-plugin</artifactId>
<executions>
<execution>
<phase>deploy</phase>
<goals>
<goal>deploy-file</goal>
</goals>
<configuration>
<packaging>jar</packaging>
<generatePom>true</generatePom>
<url>https://mycompany.jfrog.io/artifactory/my-app-libs-release</url>
<artifactId>${project.artifactId}</artifactId>
<groupId>${project.groupId}</groupId>
<version>${project.version}</version>
<file>${project.build.directory}/${project.artifactId}-${project.version}.jar</file>
</configuration>
</execution>
</executions>
</plugin>
- 當我運行時
mvn deploy，專案顯示 401 Unauthorized 錯誤，但該工件已部署并且可以在 jFrog 包中找到。 - 我在專案 my-second-app 中添加了依賴，運行時可以下載依賴
mvn install
<dependency>
<groupId>com.mycompany.app</groupId>
<artifactId>my-app</artifactId>
<version>0.0.6-SNAPSHOT</version>
</dependency>
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy-file (default) on project my-app: Failed to retrieve remote metadata com.mycompany.app:my-app:0.0.6-SNAPSHOT/maven-metadata.xml: Could not transfer metadata com.mycompany.app:my-app:0.0.6-SNAPSHOT/maven-metadata.xml from/to remote-repository (https://myurl.jfrog.io/artifactory/my-app-libs-release): authentication failed for https://mycompany.jfrog.io/artifactory/my-app-libs-release/com/mycompany/app/my-app/0.0.6-SNAPSHOT/maven-metadata.xml, status: 401 Unauthorized -> [Help 1]

Does anyone know what I have been missing? Why I got the 401 unauthorized error? I have added the credentials in settings.xml, my understanding is it is not required to add any credential in project level.
Any help is appreciated, thanks in advance.

Maven 配置了在大多數情況下都可以使用的內置默認值，并且標準的 Maven 感知存盤庫服務器（如 Nexus 和 Artifactory）將以最少的配置與它們一起使用。
洗掉您擁有的自定義配置maven-deploy-plugin，讓它使用默認設定。相反，為您的服務器添加一個distributionManagement帶有的部分repository，并確保您的~/.m2/settings.xml檔案中有匹配的憑據。
