JHipster - 运行liquibase:diff由于"拒绝访问"而失败

Question

在JHipster中向实体添加字段时,最后一步(使用MySQL时)正在运行

./mvnw编译liquibase:diff

根据https://jhipster.github.io/development/上的文档

但是,这对我相当简单的安装不起作用,因为该进程不使用正确的MySQL用户并通过.我的应用程序在开发配置文件中运行良好,但不是这样.

Liquibase从哪里获得凭证？

下面你可以看到输出.

它首先出现使用正确的设置.我的数据库被称为"imicloud",但后来错误是:

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: NO) 

显然我正在使用MySQL的密码.

如何解决这个问题？

我想我错过了必要的设置步骤,因为这是我第一次使用该liquibase:diff命令.

mvn liquibase您可以pom.xml在liquibase插件的配置标记中找到命令使用的凭据.在的部分pom.xml是这样的:

        <plugin>
            <groupId>org.liquibase</groupId>
            <artifactId>liquibase-maven-plugin</artifactId>
            <version>${liquibase.version}</version>
            <configuration>
                <changeLogFile>src/main/resources/config/liquibase/master.xml</changeLogFile>
                <diffChangeLogFile>src/main/resources/config/liquibase/changelog/${maven.build.timestamp}_changelog.xml</diffChangeLogFile>
