為Liquibase任務添加Gradle任務

Question

我正在將JHipster 4.5.4和Gradle用作構建系統，並想添加Gradle Tasks以執行Liquibase任務，例如驗證或重置。 我使用了JHipster附帶的liquibaseDiffChangelog任務作為模板。 此任務的定義如下：

task liquibaseDiffChangelog(dependsOn: compileJava, type: JavaExec) {
    group = "liquibase"

    if (OperatingSystem.current().isWindows()) {
        dependsOn pathingLiquibaseJar
        doFirst {
            classpath = files(pathingLiquibaseJar.archivePath)
        }
    } else {
        classpath sourceSets.main.runtimeClasspath
        classpath configurations.liquibase
    }
    main = "liquibase.integration.commandline.Main"

    args "--changeLogFile=src/main/resources/config/liquibase/changelog/" + buildTimestamp() +"_changelog.xml"
    args "--referenceUrl=hibernate:spring:at.project.domain?dialect=org.hibernate.dialect.MySQL5InnoDBDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy"
    args "--username=testapp_db_user"
    args "--password=secret"
    args "--url=jdbc:mysql://localhost:3306/testapp_db"
    args "--driver=com.mysql.jdbc.Driver"
    args "diffChangeLog"
}

我從簡單地用validate交換diffChangeLog開始，然后收到類路徑錯誤。 我還添加了一個classpath參數，並最終得到了這樣的任務定義：

task liquibaseValidate(dependsOn: compileJava, type: JavaExec) {
    group = "liquibase"

    if (OperatingSystem.current().isWindows()) {
        dependsOn pathingLiquibaseJar
        doFirst {
            classpath = files(pathingLiquibaseJar.archivePath)
        }
    } else {
        classpath sourceSets.main.runtimeClasspath
        classpath configurations.liquibase
    }
    main = "liquibase.integration.commandline.Main"

    args "--changeLogFile=./build/resources/main/config/liquibase/master.xml"
    args "--referenceUrl=hibernate:spring:at.project.domain?dialect=org.hibernate.dialect.MySQL5InnoDBDialect&hibernate.physical_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy&hibernate.implicit_naming_strategy=org.springframework.boot.orm.jpa.hibernate.SpringImplicitNamingStrategy"
    args "--username=testapp_db_user"
    args "--password=secret"
    args "--url=jdbc:mysql://localhost:3306/testapp_db"
    args "--driver=com.mysql.jdbc.Driver"
    args "--classpath=./build/resources/main/config/liquibase/changelog/"
    args "validate"
}

讀取主文件，因為它提到了正確的文件名，所以這部分很好。 但是它無法識別在master.xml文件中引用的實際變更集文件的路徑。 這是錯誤消息：

如何正確添加類路徑？

與此JHipster問題相關 ，您需要從master.xml（位於src/main/resources/config/liquibase/master.xml ）的更改日志路徑中刪除classpath: 。 這將允許您使用除liquibaseDiffChangeLog之外的其他liquibase任務。 此問題應在下一版本（v4.6.2 +）中修復。
