Problem

I'm getting the "Hard coded password found here" exception.

Code

import static java.util.Arrays.asList;

import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;
import com.google.api.client.http.javanet.NetHttpTransport;
import com.google.api.client.json.jackson2.JacksonFactory;
import com.google.api.services.drive.DriveScopes;
import com.google.api.services.fusiontables.FusiontablesScopes;
import java.io.IOException;
import java.security.GeneralSecurityException;
import java.security.KeyStore;
import java.security.PrivateKey;
import java.util.List;
import org.springframework.beans.factory.annotation.Value;

/** Creates and stores credentials for google oauth2 services. */
class GoogleOauth2CredentialsService {

  @Value("${p12Name}")
  private String p12Name;

  @Value("${p12Alias}")
  private String p12Alias;

  @Value("${p12Password}")
  private String p12Token;

  private static final List<String> SCOPES =
      asList(
          "https://spreadsheets.google.com/feeds",
          "https://docs.google.com/feeds",
          DriveScopes.DRIVE);
  
  GoogleCredential getAppCredentials() throws IOException, GeneralSecurityException {
    KeyStore ks = KeyStore.getInstance("PKCS12");
    ks.load(this.getClass().getClassLoader().getResourceAsStream(p12Name), p12Token.toCharArray());
    PrivateKey key = (PrivateKey) ks.getKey(p12Alias, p12Token.toCharArray());

    return new GoogleCredential.Builder()
        .setTransport(new NetHttpTransport())
        .setJsonFactory(new JacksonFactory())
        .setServiceAccountPrivateKey(key)
        .setServiceAccountScopes(SCOPES)
        .build();
  }
}
