尝试将目标属性传递给FlywayMigration gradle任务
gradle flywayMigrate -d -Pflyway.target='1.0.0'
或
gradle flywayMigrate -d -Pflyway.target=1.0.0
或
flyway {
url = 'jdbc:h2:file:target/foobar'
user = 'sa'
target = '1'}
以org.codehaus.groovy.runtime.typehandling.GroovyCastException
失败09:08:25.855 [ERROR] [org.gradle.BuildExceptionReporter] Caused by: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '1.0.0' with class 'java.lang.String' to class 'com.googlecode.flyway.core.api.MigrationVersion'
使用的版本和平台：
'com.googlecode.flyway:flyway-gradle-plugin:2.2'
gradle -version
Gradle 1.6
Gradle build time: Tuesday 07 May 2013 9:12:14 AM
Groovy: 1.8.6
Ant: Apache Ant(TM) version 1.8.4 compiled on May 22 2012
Ivy: 2.2.0

OS: Mac OS X 10.8.3 x86_64
这似乎会影响何时尝试设置两个属性：
仔细看看这两种方法都覆盖了接受不同类型作为参数的setter：
Sets the version to tag an existing schema with when executing init.
Parameters:
initVersion The version to tag an existing schema with when executing init. (default: 1)
740
741 public void setInitVersion(MigrationVersion initVersion) {
742 this.initVersion = initVersion;
743 }
Sets the version to tag an existing schema with when executing init.
Parameters:
initVersion The version to tag an existing schema with when executing init. (default: 1)
749
750 public void setInitVersion(String initVersion) {
751 this.initVersion = new MigrationVersion(initVersion);
752 }
然而，似乎在gradle目标设置中，当在这两个方法上调用setter时，那些优先级groovy与正确的覆盖类型不匹配：
/**
* Sets this property on this Flyway instance if a value has been defined.
* @param flyway The Flyway instance.
* @param property The property to set.
*/
private void propSet(Flyway flyway, String property) {
def value = prop(property);
if (value != null) {
flyway[property] = value;
}
}
