Question

我试图通过以下方式创建 AWSCredentials 对象：

AWSCredentials cred =  new ProfileCredentialsProvider("Rafael_Nascimento").getCredentials();

凭据文件位于〜/ .aws 文件夹（Linux），如下所示：

# Move this credentials file to (~/.aws/credentials)
# after you fill in your access and secret keys in the default profile
# WARNING: To avoid accidental leakage of your credentials,
#          DO NOT keep this file in your source directory.
[default]
aws_access_key_id =  <default_key>
aws_secret_access_key = <default_secret_key>
[Rafael_Nascimento]
aws_secret_access_key = <secret_key_Rafael_Nascimento>
aws_access_key_id = <key_Rafael_Nascimento>

当我运行代码时，我就到了那一行：

Exception in thread "main" java.lang.IllegalArgumentException: profile file cannot be null
    at com.amazonaws.util.ValidationUtils.assertNotNull(ValidationUtils.java:37)
    at com.amazonaws.auth.profile.ProfilesConfigFile.<init>(ProfilesConfigFile.java:142)
    at com.amazonaws.auth.profile.ProfilesConfigFile.<init>(ProfilesConfigFile.java:133)
    at com.amazonaws.auth.profile.ProfilesConfigFile.<init>(ProfilesConfigFile.java:100)
    at com.amazonaws.auth.profile.ProfileCredentialsProvider.getCredentials(ProfileCredentialsProvider.java:135)

可能有什么不对？谢谢！

我的应用程序无法找到凭据文件。我通过创建全局环境变量（在 / etc / environment 文件中）解决了这个问题：的 AWS_CREDENTIAL_PROFILES_FILE =＆＃34; /home/rafael/.aws/credentials"

确保您的应用程序可以看到变量：

System.out.println(System.getenv("AWS_CREDENTIAL_PROFILES_FILE")); //output: /home/rafael/.aws/credentials

ProfileCredentialsProvider：java.lang.IllegalArgumentException：配置文件不能为null
