Gradle Plugin Execution Order - gradle

Question

I have written this gradle file
group 'com.abhi'
version '1.0-SNAPSHOT'
apply plugin: 'java'
apply plugin: 'org.flywaydb.flyway'
sourceCompatibility = 1.8
buildscript {
repositories {
mavenCentral()
}
dependencies {
classpath 'org.flywaydb:flyway-gradle-plugin:3.2.1'
classpath 'org.jooq:jooq-codegen:3.7.1'
classpath 'com.h2database:h2:1.4.177'
}
}
repositories {
mavenCentral()
}
dependencies {
compile group: 'org.jooq', name: 'jooq', version: '3.7.1'
compile group: 'org.jooq', name: 'jooq-meta', version: '3.7.1'
compile group: 'org.jooq', name: 'jooq-codegen', version: '3.7.1'
runtime group: 'com.h2database', name: 'h2', version: '1.4.177'
}
flyway {
url = 'jdbc:h2:file:target/foobar'
user = 'sa'
}
def writer = new StringWriter()
def xml = new groovy.xml.MarkupBuilder(writer)
.configuration('xmlns': 'http://www.jooq.org/xsd/jooq-codegen-3.7.0.xsd') {
jdbc() {
driver('org.h2.Driver')
url('dbc:h2:file:target/foobar')
user('sa')
password('')
}
generator() {
database() {
}
generate() {
}
target() {
packageName('com.abhi.jooq.models')
directory('src/main/java')
}
}
}
// Run the code generator
// ----------------------
org.jooq.util.GenerationTool.generate(
javax.xml.bind.JAXB.unmarshal(new StringReader(writer.toString()), org.jooq.util.jaxb.Configuration.class)
)
when I say gradle compile it throws an exception
Could not load schemata
java.lang.NullPointerException
at org.jooq.impl.MetaImpl.meta(MetaImpl.java:120)
at org.jooq.impl.MetaImpl.getCatalogs(MetaImpl.java:143)
at org.jooq.impl.MetaImpl.getSchemas(MetaImpl.java:168)
at org.jooq.util.jdbc.JDBCDatabase.getSchemasFromMeta(JDBCDatabase.java:135)
at org.jooq.util.jdbc.JDBCDatabase.getSchemata0(JDBCDatabase.java:124)
at org.jooq.util.AbstractDatabase.getSchemata(AbstractDatabase.java:279)
I think the problem is that the code at the bottom of the script executes much before the "flyway" plugin.
Is there a way I can ensure that the code below is executed only after the flyway plugin has executed?

Answer 1

Yes, if you suppose, the problem is in execution order, then you can modify it, just like with any other tasks. Take a look at the documentation of the flyway plugin. According to it, this plugin adds some extra tasks to your build script, for thos one tasks are: flywayMigrate, flywayClean etc. You can make any of your tasks depending (with dependsOn option) on the tasks form this plugin and make them running just after the plugin's job is done.
