Maven 嵌入器：无法解析编译器依赖性 - 没有可用的连接器工厂

Question

我有 Maven 项目 A 和 B。项目 A 使用 maven embedder 3.2.5 并用它构建项目 B。

MavenCli mavenCli = new MavenCli();
mavenCli.doMain(new String[] {"package"}, "C:\Users\JohnDoe\Desktop\abc", System.out, System.out);

但是我遇到了异常：

Plugin org.apache.maven.plugins:maven-compiler-plugin:3.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-compiler-plugin:jar:3.1: Could not transfer artifact org.apache.maven.plugins:maven-compiler-plugin:pom:3.1 from/to central (https://repo.maven.apache.org/maven2): No connector factories available

我查看了我的本地存储库文件夹，确实没有插件版本 3.1。如果我手动将它放在那里，则构建成功。但是 AFAIK maven 应该自动下载所有必要的插件。但它不会发生。

Answer 1

添加这些依赖项解决了我的问题

 <dependency>
  <groupId>org.eclipse.aether</groupId>
  <artifactId>aether-connector-basic</artifactId>
  <version>1.0.2.v20150114</version>
</dependency>
<dependency>
  <groupId>org.eclipse.aether</groupId>
  <artifactId>aether-transport-wagon</artifactId>
  <version>1.0.2.v20150114</version>
</dependency>
<dependency>
  <groupId>org.apache.maven.wagon</groupId>
  <artifactId>wagon-http</artifactId>
  <version>2.8</version>
  </dependency>
<dependency>
  <groupId>org.apache.maven.wagon</groupId>
  <artifactId>wagon-provider-api</artifactId>
  <version>2.8</version>
</dependency>

Answer 2

如果要部署，还需要这个依赖：

<dependency
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.3</version>
</dependency>

Answer 3

我将我的应用程序（Spring Boot 2.3，JDK8/11）更新为具有以下依赖项的最新 Maven Embedded 3.6.3 版本：

<!-- Maven Embedder -->
<dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-embedder</artifactId>
    <version>3.6.3</version>
</dependency>
<dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-compat</artifactId>
    <version>3.6.3</version>
</dependency>
<dependency>
    <groupId>org.apache.maven.wagon</groupId>
    <artifactId>wagon-http</artifactId>
    <version>3.3.4</version>
</dependency>
<dependency>
    <groupId>org.eclipse.aether</groupId>
    <artifactId>aether-connector-basic</artifactId>
    <version>1.1.0</version>
    <scope>runtime</scope>

    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-simple</artifactId>

Answer 4

使用这些依赖项

<dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-embedder</artifactId>
    <version>3.6.3</version>
</dependency>
<dependency>
    <groupId>org.apache.maven</groupId>
    <artifactId>maven-compat</artifactId>
    <version>3.6.3</version>
</dependency>
<dependency>
    <groupId>org.apache.maven.resolver</groupId>
    <artifactId>maven-resolver-connector-basic</artifactId>
    <version>1.4.1</version>
</dependency>
<dependency>
    <groupId>org.apache.maven.resolver</groupId>
    <artifactId>maven-resolver-transport-http</artifactId>
    <version>1.4.1</version>
</dependency>

使用 Apache Maven Artifact Resolver 而不是存档的 Aether。
