NoClassDefFoundError: org/apache/commons/lang/exception/NestableException

[Padmahas]

Hello,

Yesterday I downloaded googleads-java-lib-v3.9.0 maven code sample archive, imported to STS (Eclipse based IDE) and configured JSON path, Network code and Application name. Now any example I try to run I'm getting "Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/lang/exception/NestableException". I searched in pom.xml for apache.commons but there is no such dependencies mentioned. How to fix this issue.

Thank you.

Hi,

The dependency on commons-lang:commons-lang:2.6 is defined in modules/ads_lib/pom.xml. For some reason, that artifact doesn't include the word 'apache' in it, perhaps for the sake of brevity.

In your Eclipse setup, are you using maven or adding dependencies manually? If you're adding dependencies manually, then I recommend downloading the dfp-axis-jars-and-examples tarball from the Releases page. That tarball contains a lib directory with JARs for each dependency.

Hello,

I think there is some misunderstanding. The pom.xml which is present in the downloaded example doesn't contain such a large list of dependencies. I downloaded example code from here, with the name dfp-axis-maven-and-examples. Are you mentioning the same?

Thank you.

Hi,

The pom in the tarball you mentioned has a dependency on com.google.api-ads:ads-lib:3.9.0, which in turn declares a dependency on the commons-lang dependency I mentioned. Therefore, maven should add commons-lang to your classpath.

Does Eclipse STS propagate dependencies to projects as described in the Maven docs, or does it only include direct dependencies for your project?

Hi,

Just checking in -- were you able to resolve this issue?

Hey Josh, Sorry I've not made any progress yet and I didn't get your question about propagating dependencies in STS. I don't know what's the behavior of Maven. I'm using Maven installed inside STS by default. Please let me know how can I find that behavior or any other way of resolving this issue. One more thing if this helps, I'm on Ubuntu 16.04, 64 bit OS.

Thank you.

Hi,

Provided the dependencies in a project's pom.xml file either have a dependency scope of compile or runtime (as is the case with the examples projects for this library), Maven should automatically add the following dependencies to the classpath:

• Dependencies directly mentioned in the pom.xml file
• Dependencies of the dependencies directly mentioned in the pom.xml file
• Dependencies of the dependencies of the dependencies directly mentioned in the pom.xml file
• and so on...

One suggestion for determining if the problem you're experiencing is due to STS is to try running an example from the command line as mentioned in the README here. For example, for DFP you could run the following command from the project's directory (where its pom.xml file resides):

 mvn -X exec:java -Dexec.mainClass="dfp.axis.v201708.companyservice.GetAllCompanies"

If that works (the output ends with BUILD SUCCESS), then the issue lies with STS.

Hi,

I'm closing this since I haven't seen any further comments in the last month. If you're still encountering problems, feel free to reopen with the latest details.
