如何设置liquibase类路径

Question

我创建了一个JHipster项目。我想手动运行liquibase变更集。默认情况下，变更集包含在类路径中。更新日志在src/main/resources/config/liquibase/master.xml，变更集在src/main/resources/config/liquibase/changelog。

<?xml version="1.0" encoding="utf-8"?>
<databaseChangeLog
    xmlns="http://www.liquibase.org/xml/ns/dbchangelog"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.liquibase.org/xml/ns/dbchangelog http://www.liquibase.org/xml/ns/dbchangelog/dbchangelog-3.5.xsd">

    <include file="classpath:config/liquibase/changelog/00000000000000_initial_schema.xml" relativeToChangelogFile="false"/>
    <!-- jhipster-needle-liquibase-add-changelog - JHipster will add liquibase changelogs here -->
    <!-- jhipster-needle-liquibase-add-constraints-changelog - JHipster will add liquibase constraints changelogs here -->
</databaseChangeLog>

运行时mvn liquibase:update，出现错误，因为即使文件存在，变更集也不在类路径中：

[ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:3.5.3:update (default-cli) on project playground: Error setting up or running Liquibase: liquibase.exception.SetupException: classpath:config/liquibase/changelog/00000000000000_initial_schema.xml does not exist -> [Help 1]

因此，我尝试通过设置类路径从命令行运行。

liquibase --classpath=src/main/resources --classpath=postgresql-42.1.3.jar 
--url=jdbc:postgresql://localhost:5432/playground 
--driver=org.postgresql.Driver 
--changeLogFile=src/main/resources/config/liquibase/master.xml 
--username playground --password=***** update

具有相同的错误： Unexpected error running Liquibase: classpath:config/liquibase/changelog/00000000000000_initial_schema.xml does not exist

一种解决方法是删除classpath:包含部分中的引用，但是我希望避免每次使用jhipster entity或时jhipster添加变更集时都编辑文件jhipster import-jdl。

解决方案是mvn process-resources在运行liquibase命令之前运行，因此下面的文件src/main/resources将在该target/classes文件夹中。然后classpath:按照https://github.com/jhipster/generator-jhipster/pull/6121中的说明删除该部分
