Question

在创建用户定义的函数期间，我在Win64环境中遇到错误。我正在使用flyway执行以下简单脚本：

CREATE ALIAS TRANSLATE_NAME AS $$
String TRANSLATE_NAME(String value) {
  ...
return null;
}
$$

我收到以下错误：

java.io.IOException: CreateProcess error=2, The system cannot find the file specified

17:10:38 ERROR (ApacheCommonsLog.java:51) - com.googlecode.flyway.core.api.FlywayException: 
Error executing statement at line 1: 
CREATE ALIAS TRANSLATE_NAME AS $$

String TRANSLATE_NAME(String value) {
return null;
}
$$

这仅出现在Win64上，无论是在32位Linux还是32位Windows上。

有什么想法吗？我会很感激！请！

Answer 1

H2需要在类路径中的JDK（类路径中的tools.jar），或者javac需要作为外部进程使用。要查明类javac是否在类路径中，请打开命令提示符并键入javac [Enter]。

Answer 2

就我而言，JAVA_HOME被定义为一个环境变量，并指向错误的JRE（没有javac命令）。我删除它，因为它不再需要，并且做了伎俩。虽然这不太可能是您的特定情况，但它证明这与解决jdks路径的环境变量有关。
