Maven嵌入式部署不使用org.apache.httpcomponents.httpclient 4.4版

Question

在我的应用程序中,我必须(mvn)以编程方式部署工件.我是在maven-embedder工件和一些非常简单的代码的帮助下完成的:

MavenCli client = new MavenCli();
int result = client.doMain(new String[] { "deploy" }, "C:/some/path/to/my/pom", System.out, System.out);

为了能够做到这一点,我不得不将以下依赖项添加到我的pom:

<dependency>
  <groupId>org.apache.maven</groupId>
  <artifactId>maven-embedder</artifactId>
  <version>3.2.5</version>
</dependency>
<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>
<dependency>
  <groupId>org.apache.httpcomponents</groupId>
  <artifactId>httpclient</artifactId>
  <version>4.3</version>
</dependency>

问题是,当我将httpclient的版本更改为4.4版(最新版本)时,尝试部署时出现以下错误:

4840 [main] WARN Sisu  - Error injecting:   org.apache.maven.wagon.providers.http.HttpWagon
    java.lang.NoClassDefFoundError: org/apache/http/ssl/TrustStrategy
    at java.lang.ClassLoader.defineClass1(Native Method)
    ...
Caused by: java.lang.ClassNotFoundException:   org.apache.http.ssl.TrustStrategy
    at java.net.URLClassLoader$1.run(URLClassLoader.java:372)   
    ... 72 more

任何人都有一个想法,为什么部署在org.apache.httpcomponents.httpclient的4.3.x版本上工作正常并且在版本4.4中失败？

Answer 1

我怀疑HttpCore的版本？HttpClient所基于的,仍然解析为4.3.x. 尝试将其明确设置为4.4

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.4</version>
</dependency>
