他のプロジェクトに存在するクラスのオブジェクトを作成中にClassNotFoundExceptionが発生しました。Spring

Question

他のプロジェクトでクラスのオブジェクトを作成しようとしています。

プロジェクトAにはTestBeanが含まれています import java.io.Serializable;私がしようとしたとき、私はプロジェクトBにプロジェクトBが

build.gradle

apply plugin: 'java' 
apply plugin: 'eclipse' 
apply plugin: 'war' 

repositories{ 
    jcenter{ 
     url "http://jcenter.bintray.com/" 
    } 
} 

dependencies {  

    compile project(':projectA') 
    runtime ':projectA' 
} 

プロジェクトBのsettings.gradle

include(':projectA') 
project(':projectA').projectDir = new File('/Users/kegupta/Framework/projectA/') 

rootProject.name = 'projectA' 

これをアクセスしようとしています

import com.fasterxml.jackson.annotation.JsonCreator; 
import com.fasterxml.jackson.annotation.JsonProperty; 

public class TestBean implements Serializable{ 

    private static final long serialVersionUID = 1L; 
    private String name; 
    private Integer age; 

    @JsonCreator 
    public TestBean(@JsonProperty("name") String name, @JsonProperty("age") Integer age) { 
     this.name = name; 
     this.age = age; 
    } 

    public TestBean() { 
     // TODO Auto-generated constructor stub 
    } 
    public String getName() { 
     return name; 
    } 
    public void setName(String name) { 
     this.name = name; 
    } 
    public Integer getAge() { 
     return age; 
    } 
    public void setAge(Integer age) { 
     this.age = age; 
    } 

} 

残りのAPIを介してProjectBの一部のメソッドでTestBeanにアクセスすると、エラーが発生します。

エラーに詳しい方。どんな助けも高く評価されます。

ProjectBのクラスパスに.classファイルを追加すると、私の問題が解決しました。

sourceSets { 
     main { 
     output.resourcesDir = '{Path to projectB}/res' 
     output.classesDir = '{Path to projectB}//bin' 
     } 
}
