Question

我正在尝试从Java类调用maven。

我的代码：

import java.io.File;
import java.util.Arrays;

import javax.xml.ws.spi.Invoker;

import org.apache.maven.shared.invoker.DefaultInvocationRequest;
import org.apache.maven.shared.invoker.DefaultInvoker;
import org.apache.maven.shared.invoker.InvocationRequest;
import org.apache.maven.shared.invoker.MavenInvocationException;

public class MavenProjectBuilder implements ProjectBuilder{

    public void BuildProject(String buildPath, String bugID) {

        InvocationRequest request = new DefaultInvocationRequest();
        request.setPomFile(new File(buildPath));
        request.setGoals(Arrays.asList( "clean", "install" ));

        DefaultInvoker invoker = new DefaultInvoker();

        try {
            invoker.execute(request);
        } catch (MavenInvocationException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }


    }

}

返回以下错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/codehaus/plexus/util/cli/StreamConsumer
    at autoEvoSuite.MavenProjectBuilder.BuildProject(MavenProjectBuilder.java:21)
    at autoEvoSuite.Main.<init>(Main.java:110)

我做了一些研究，发现它可能是一个缺失的依赖，但不应该Maven自动下载所有缺失的那些？

Answer 1

请检查POM.xml中是否存在以下依赖项，直到您的pom文件中定义了依赖项，该jar文件将不会下载到本地存储库。

<dependency>
  <groupId>org.codehaus.plexus</groupId>
  <artifactId>plexus-utils</artifactId>
  <version>3.0.17</version>
</dependency>
