Unable to authenticate GoogleAdsClient over Java 1.8

[ahmadhashlamoun]

I'm trying to use Google Ads API, I already have my ads.properties file ready, and I added the following dependencies to my pom file:

<dependency> <groupId>com.google.api-ads</groupId> <artifactId>google-ads</artifactId> <version>9.0.0</version> </dependency>
<dependency> <groupId>com.google.guava</groupId> <artifactId>guava</artifactId> <version>27.0-jre</version> </dependency>
<dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpcore</artifactId> <version>4.4.8</version> </dependency>

But when I try to run the code like this:
File file = new File(this.getClass().getClassLoader().getResource("/ads.properties").getFile());
GoogleAdsClient googleAdsClient = GoogleAdsClient.newBuilder().fromPropertiesFile(file).build();

I get the following error:
org.glassfish.jersey.server.ContainerException: java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkArgument(ZLjava/lang/String;Ljava/lang/Object;)V

Is there a problem with the library? And how could I fix it?
Would this be a problem with my credentials?

[nwbirnie]

This is a common version conflict with the Guava dependency. Which version of the client library are you using? If it's 9.0.0 your version of Guava should be 28.2-android

[ahmadhashlamoun]

@nwbirnie I tried 28.2-jre but still same issue, I'm not using it for android tho, it's for our general APIs
Any clue?
What else versions I may use?

[nwbirnie]

Please use 28.2-android. We use the android version because we explicitly want to support usage from android (see details).

[ahmadhashlamoun]

@nwbirnie Still same error!
Here's my maven dependencies:

        </dependency>

@nwbirnie what do you think?

[ahmadhashlamoun]

If I want to use version 8, which Guava version would work?

[nwbirnie]

If you move the Guava dependency to the top of the list it should work.

  <dependencies>
    <dependency>
      <groupId>com.google.guava</groupId>
      <artifactId>guava</artifactId>
      <version>28.2-android</version>
    </dependency>
    <dependency>
      <groupId>com.google.oauth-client</groupId>
      <artifactId>google-oauth-client-servlet</artifactId>
      <version>1.19.0</version>
      <exclusions>
        <exclusion>
          <artifactId>servlet-api</artifactId>
          <groupId>javax.servlet</groupId>
        </exclusion>
      </exclusions>
    </dependency>
    <dependency>
      <groupId>com.google.apis</groupId>
      <artifactId>google-api-services-oauth2</artifactId>
      <version>v2-rev83-1.19.0</version>
    </dependency>
    <dependency>
      <groupId>com.google.http-client</groupId>
      <artifactId>google-http-client-jackson</artifactId>
      <version>1.19.0</version>
    </dependency>
    <dependency>
      <groupId>com.google.api-ads</groupId>
      <artifactId>google-ads</artifactId>
      <version>9.0.0</version>
    </dependency>
    <dependency>
      <groupId>org.apache.httpcomponents</groupId>
      <artifactId>httpcore</artifactId>
      <version>4.4.8</version>
    </dependency>
  </dependencies>

Are you using Intellij by any chance? It appears that maven CLI doesn't require this reordering, but IntelliJ does for some reason...

If you want to see the required dependencies for a version, simply add a dependency on that version, then run mvn dependency:tree -Dverbose and look for the entries you're interested in under google-ads. In the case of 8.0.0 the Guava dependency is also 28.2-android.

[ahmadhashlamoun]

@nwbirnie yes I'm using IntelliJ for this.
I tried putting the Guava dependency on top, and still the same issue :/

Here's a screenshot from our dependencies tree, please check if we're making a mistake here:\

Is this seems right? And why it's saying com.google.guava:guava:jar:28.2-android:compile - omitted for duplicate:
[INFO]+- com.google.api-ads:google-ads:jar:9.0.0:compile [INFO] | +- com.google.api:gax:jar:1.57.1:compile [INFO] | | +- (com.google.guava:guava:jar:28.2-android:compile - omitted for duplicate) [INFO] | | +- (com.google.code.findbugs:jsr305:jar:3.0.2:compile - omitted for duplicate)

I just have it once in my dependencies file

[nwbirnie]

Can you create a repo with a minimal failing example please?

[ahmadhashlamoun]

@nwbirnie it's so hard doing so, esp the project is huge and not easy to do so, but I can provide a full image of dependencies tree if that would make it easier?

[ahmadhashlamoun]

@nwbirnie check above

[nwbirnie]

I only need the minimal dependencies required to produce an error case, similar to what you pasted earlier.

[nwbirnie]

To give you a starting point, here is the pom.xml and test case I created earlier which fixes the dependency list you originally sent over.

[ahmadhashlamoun]

@nwbirnie you mean something like so?

[nwbirnie]

This pom works correctly for me in IntelliJ.

On the command line I had to change packaging war -> pom, but it does work there too.

[nwbirnie]

Are you possibly running an old version of IntelliJ? Or is there something about your war deployment that might be causing the issue?

Also have you rerun the IntelliJ maven importer since changing the pom?
