java - Achilles 4.2.0编译错误 - 找不到符号symbol : class Table location: package info. archinnov.achilles.annotations

Question

我在编译简单的 achilles maven 项目时遇到一些问题。我的 pom.xml:

<dependencies>
        <dependency>
            <groupId>info.archinnov</groupId>
            <artifactId>achilles-core</artifactId>
            <version>4.2.0</version>
        </dependency>
        <dependency>
            <groupId>info.archinnov</groupId>
            <artifactId>achilles-model</artifactId>
            <version>4.2.0</version>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <configuration>
                    <source>1.8</source>
                    <target>1.8</target>
                    <useIncrementalCompilation>false</useIncrementalCompilation>
                </configuration>
            </plugin>
        </plugins>
    </build>

我像这样配置了 Intellij Idea Annotation Process:https://github.com/doanduyhai/Achilles/wiki/IDE-configuration

当我尝试运行 mvn -X clean install 时，我遇到了一些编译错误:

[ERROR] /home/konrad/Pulpit/CassandraAchilles/target/generated-sources/annotations/info/archinnov/achilles/generated/meta/entity/User_AchillesMeta.java:[49,69] cannot find symbol
  symbol: class User

  symbol:   class User
  location: class info.archinnov.achilles.generated.meta.entity.User_AchillesMeta

用户是我的实体:

import info.archinnov.achilles.annotations.Column;
import info.archinnov.achilles.annotations.PartitionKey;
import info.archinnov.achilles.annotations.Table;

@Table(keyspace = "example", table = "user")
public class User {

    @PartitionKey
    private Long id;

    @Column("fname")
    private String firstName;

    @Column("age")
    private int age;


    public User() {
    }

    public User(Long id, String firstName, int age) {
        this.id = id;
        this.firstName = firstName;
        this.age = age;
    }

    public Long getId() {
        return id;
    }

    public void setId(Long id) {
        this.id = id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }
}

我做错了什么？

对我来说将User类包含到包中解决了问题。

问题似乎出在代码的生成方式上，正如 IDE configuration page 末尾所解释的那样。你提到:

In some cases, if the processor does not generate the code correctly, you may need to do a clean build with Maven (this is actually the only method that is working 100% in any case). For this open a shell terminal and type mvn clean compile then go back to the IDE and refresh your project, you should see the generated code.
