Question

我尝试使用flyway和gradle设置数据库迁移。任务失败，出现以下错误

* Exception is:

我尝试了以下

echo $GRADLE_OPTS
-Xmx2048m

echo $JAVA_OPTS
-Xmx2048m

也为gradle属性添加了一些设置：

cat ~/.gradle/gradle.properties 
org.gradle.parallel=true
org.gradle.daemon=true
org.gradle.jvmargs=-Xms1024m -Xmx2048m

那没有用，有什么建议吗？

Answer 1

buildscript {
    dependencies {
        classpath 'mysql:mysql-connector-java:5.1.34'
    }
}


plugins {
    id "org.flywaydb.flyway" version "4.0.3"
}

flyway {
    url = 'jdbc:mysql://localhost:3306/mydb'
    user = 'root'
    password = 'abc!23'
    schemas = ['mydb']
    baselineVersion = 1
    baselineDescription = "Baselining myDB Schema"
}

基本上我使用的是一个非常旧版本的FlyWay导致Java堆空间 - 我的坏。上面的构建脚本可以是任何想要在MYSQL上使用FlyWay执行数据库迁移的人的资源。

Gradle flywayMigrate给出内存不足异常
