使用java回调运行Flyway迁移任务时发生ClassNotFoundException

flyway maven

ThatDataGuy · 技术社区 · 5 年前

我正在尝试实现FlyWay java回调。然而,弗利似乎找不到我的课。

[ERROR] Failed to execute goal org.flywaydb:flyway-maven-plugin:6.0.0-beta:migrate (default-cli) on project odin_build: org.flywaydb.core.api.FlywayException: Unable to instantiate class ch.x.dp.test1 : ch.x.dp.test1 -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.flywaydb:flyway-maven-plugin:6.0.0-beta:migrate (default-cli) on project odin_build: org.flywaydb.core.api.FlywayException: Unable to instantiate class ch.x.dp.test1 : ch.x.dp.test1
/snip.../
Caused by: java.lang.ClassNotFoundException: ch.x.dp.test1
    at org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy.loadClass (SelfFirstStrategy.java:50)

看来飞行道找不到这个班了。

这里是我的java类:

package ch.x.dp;

import org.flywaydb.core.api.callback.Callback;
import org.flywaydb.core.api.callback.Context;
import org.flywaydb.core.api.callback.Event;

public class test1 implements Callback {

    public test1() {
        System.out.println("sldhksjhdkghd");
    }

    public boolean supports(Event event, Context context) {
        return false;
    }

    public boolean canHandleInTransaction(Event event, Context context) {
        return false;
    }

    public void handle(Event event, Context context) {
    }
}

我的pom包含以下内容:

 <dependency>
            <groupId>org.flywaydb</groupId>
            <artifactId>flyway-core</artifactId>
            <version>6.0.0-beta2</version>
        </dependency>

和

<plugins>
            <plugin>
                <groupId>org.flywaydb</groupId>
                <artifactId>flyway-maven-plugin</artifactId>
                <version>${flyway.version}</version>
                <configuration>
                    <locations>classpath:ch.x.dp,filesystem:src/main/resources/db/migration</locations>
                    <callbacks>
                        <callback>ch.x.dp.test1</callback>
                    </callbacks>
<snip/>
            </plugin>

我已经验证了我的mvn包调用在/target中创建了一个包含test1类的jar。

还有什么可能丢失?我怎么能知道那个飞行路线真的在用那个罐子?
