【问题描述】：
我正在尝试学习 Liquibase，并使用 Liquibase、Liquibase Groovy DSL 和 Liquibase Gradle 插件建立了一个简单的 Gradle 项目。
当我运行update 或updateSql 之类的任务时，会引发Unrecognized root element changeSet 错误。我做错了什么？
src/main/db/changeset.groovy 中的变更集文件包含：
databaseChangeLog {
changeSet(id: '1.0-test-changeset', author='aoife') {
createTable(tableName: 'foo', remarks: 'Foo table for testing liquibase') {
column(name: 'bar', type: 'varchar(60)', remarks: 'lots of bars')
column(name: 'baz', type: 'varchar(15)', remarks: 'even more bazes')
}
}
}
build.gradle 包含：
plugins {
id 'groovy'
id 'application'
id 'org.liquibase.gradle' version '2.0.1'
}
version = "1.0"
group = "liquitest"
mainClassName = "liquitest.LiquiTest"
repositories {
maven {
url "${nexusUrl}/maven-public"
}
}
dependencies {
compile 'org.codehaus.groovy:groovy-all:2.5.2'
compile 'com.oracle.jdbc:ojdbc8:12.2.0.1'
compile 'ch.qos.logback:logback-classic:1.2.3'
testCompile 'org.spockframework:spock-core:1.2-RC3-groovy-2.5'
liquibaseRuntime 'org.liquibase:liquibase-core:3.6.1'
liquibaseRuntime 'org.liquibase:liquibase-groovy-dsl:2.0.1'
liquibaseRuntime 'com.oracle.jdbc:ojdbc8:12.2.0.1'
}
liquibase {
activities {
main {
changeLogFile 'src/main/db/changeset.groovy'
url project.ext.oracleInstance
username project.ext.oracleUser
password project.ext.oraclePassword
}
}
}
./gradlew updateSql 的输出：
> Task :updateSQL FAILED

【问题讨论】：
-
文档说它必须是
databaseChangeLog = {。一个关闭。但我不知道这是否是你错误的原因。 -
哦，我想到了 Grails 插件，抱歉。也可以是一个函数
databaseChangeLog() {。仅适用于 grails 插件。我出去了。 -
我尝试
databaseChangeLog() { }时出现同样的错误。如果我尝试使用空的databaseChangeLog闭包，它会起作用。 -
作者后面有一个等号而不是冒号。应该是冒号。
-
很好，就是这样！把它作为一个答案，我会接受它:)
