尝试执行以下教程时：

使用Android Studio，我创建了一个Android Studio项目，并添加了具有以下内容的CheckIn.java类：

import java.util.Date;
import com.google.appengine.api.datastore.Key;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;

@Entity
public class CheckIn {
@Id
@GeneratedValue(strategy = GenerationType.IDENTITY)
private java.security.Key key;
private String placeId;
private String userEmail;
private Date checkinDate;

public java.security.Key getKey() {
    return key;
}

public String getPlaceId() {
    return placeId;
}
public void setPlaceId(String placeId) {
    this.placeId = placeId;
}

public String getUserEmail() {
    return userEmail;
}
public void setUserEmail(String userEmail) {
    this.userEmail = userEmail;
}

public Date getCheckinDate() …

我的项目布局如下:

src/
  java
  generated

src/java包含jpa实体和查询类,它们使用由hibernate元模型注释处理器生成的jpa元模型类.

将注释处理合并到java插件的最佳方法是什么？

我目前定义了以下任务,但它对compileJava有一个任务依赖,它将失败,因为某些代码依赖于注释处理器生成的类.

task processAnnotations(type: Compile) {
    genDir = new File("${projectDir}/src/generated")
    genDir.mkdirs()
    source = ['src/java']
    classpath = sourceSets.test.compileClasspath
    destinationDir = genDir
    options.compilerArgs = ["-proc:only"]
}
