如何在将jar安装到m2库中时下载jar依赖项

Question

我有一个maven插件jar，它已经构建在另一台机器上，比如test-1.0.0.jar。这个jar有多个依赖项，如apache、plexus、maven等。例如：

<dependencies>
    <dependency>
        <groupId>org.apache.maven</groupId>
        <artifactId>maven-core</artifactId>
        <version>3.3.9</version>
    </dependency>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-plugin-api</artifactId>
      <version>3.3.9</version>
    </dependency>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-compat</artifactId>
      <version>3.3.9</version>
    </dependency>   
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-embedder</artifactId>
      <version>3.3.9</version>
    </dependency>
    <dependency>
      <groupId>org.apache.maven</groupId>
      <artifactId>maven-archiver</artifactId>
      <version>2.5</version>
    </dependency>
    <dependency>
      <groupId>commons-io</groupId>
      <artifactId>commons-io</artifactId>
      <version>2.2</version>
    </dependency>
    <dependency>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-compiler-plugin</artifactId>
      <version>3.5</version>
    </dependency>
    <dependency>
      <groupId>org.apache.maven.plugin-tools</groupId>
      <artifactId>maven-plugin-annotations</artifactId>
      <version>3.4</version>
      <scope>provided</scope>
    </dependency>
    <dependency>
      <groupId>org.apache.maven.surefire</groupId>
      <artifactId>maven-surefire-common</artifactId>
      <version>2.19.1</version>
    </dependency>
    <dependency>
      <groupId>org.apache.maven.surefire</groupId>
      <artifactId>surefire-api</artifactId>
      <version>2.19.1</version>
    </dependency>
    <dependency>
        <groupId>org.codehaus.plexus</groupId>
        <artifactId>plexus-component-annotations</artifactId>
        <version>1.6</version>
    </dependency>
    <dependency>
       <groupId>org.apache.maven.surefire</groupId>
       <artifactId>surefire-junit47</artifactId>
       <version>2.19.1</version>
    </dependency>
  </dependencies>

现在我想在我的maven项目中使用这个jar，所以我将它安装到了我的本地存储库中。当我使用'mvn install: install -file‘命令安装它时，它没有下载m2存储库中jar所需的所有依赖项。所以当我在我的新maven项目中使用这个插件时，它会给我一个classNotFound异常。

[WARNING] Error injecting: com.test.status.test.MyTestCompileMojo
java.lang.NoClassDefFoundError: org/codehaus/plexus/compiler/util/scan/InclusionScanException

我的项目POM -

<project>
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.check.status</groupId>
  <artifactId>cf</artifactId>
  <version>1.0.0</version>
  <packaging>jar</packaging>
  <build>
    <plugins>
      <plugin>
        <groupId>com.test.status</groupId>
        <artifactId>test</artifactId>
        <version>1.0.0</version>
        <extensions>true</extensions>
       </plugin>
    </plugins>
  </build>
  <dependencies/>
</project>

Answer 1

您应该将test-1.0.0.jar依赖项添加到pom.xml <dependencies>中。

使用-U参数执行maven应该会强制检查远程存储库上缺少的版本和更新的快照。例如：

mvn -U clean install

实际上，执行目标dependency:resolve只会下载依赖项，而不会做任何其他事情。

mvn dependency:resolve

Answer 2

尝试将test-1.0.0.jar中的依赖项添加到maven项目中。

(pom.xml) test-1.0.0.jar  ---copy dependencies---> new maven project
