java - GOOGLE_APPLICATION_CREDENTIALS 在 JAVA 中不起作用

Question

我尝试使用 Google Speach Api

我在身份验证方面遇到了大问题。

我关注了这个tutorial ，然后导出 GOOGLE_APPLICATION_CREDENTIALS，并使用 echo 检查它，一切正常。

但是当我从第一个链接开始编写代码时出现错误:

Exception in thread "main" java.io.IOException: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

当然我检查了环境变量中的路径，即使我得到这个文件 chmod 777，也没有任何帮助。

有人遇到过类似的问题吗？

stat $GOOGLE_APPLICATION_CREDENTIALS 的输出:

但是当我重新启动计算机并调用 stat 时，我有 stat: missing operand

我的导出推荐 export GOOGLE_APPLICATION_CREDENTIALS=/home/kruczek/Pulpit/mirthconnection-59cb32bcd531.json 我通过 IDE Intellij 运行项目，在 privat static void main 旁边我们有绿色箭头来运行方法。

Answer 1

在 eclipse 中， 运行 -> 运行配置.. -> 环境选项卡

在名称下输入 GOOGLE_APPLICATION_CREDENTIALS: 在Value中输入json路径:

请确保在值中输入路径时没有输入引号。
