Solved: Re: intelliJ/Maven CS SDK Dependency Errors

rdediana · ‎06-20-2017

Hello folks.

I'm experiencing the same issue identified in the following discussion: intelliJ/Maven CS SDK issue

i'm following the getting started guide

https://developer.cisco.com/site/context-service/discover/getting-started/

Error:(6, 39) java: package com.cisco.thunderhead.connector does not exist

Error:(7, 36) java: package com.cisco.thunderhead.plugin does not exist

i've added the required dependencies to the pom.xml file:

the compiler is highlighting the <version>2.0.1</version> with an error: dependency not found

<groupId>com.cisco.thunderhead</groupId>

<artifactId>context-service-sdk</artifactId>

</dependency>

<groupId>commons-logging</groupId>

<artifactId>commons-logging</artifactId>

</dependency>

</dependencies>

I just noticed that you were using sudo to do the maven install. Check which directory intellij is using for your local maven repo. To do that, go to preferences/Build, Execution, Deployment/Build Tools/Maven. Check on the right where the local repository is pointed. Make sure that matches where the files are getting installed. Above, it looks like because you are running sudo its getting installed in /var/root/.m2/repository. IntelliJ is not likely to be running as root. IntelliJ is probably using /Users/regandediana/.m2/repository. If so, try running the mvn install:install-file command without using sudo.

cvadnais · ‎06-20-2017

Have you run step 12 in the getting started guide to install the pom file in your local maven repo? Make sure to replace the 2.x.x with the correct version - 2.0.1 in your case.

mvn install:install-file -Dfile=src/main/resources/context-service-sdk-2.x.x.jar -DgroupId=com.cisco.thunderhead -DartifactId=context-service-sdk -Dversion=2.x.x -Dpackaging=jar -DpomFile=src/main/resources/context-service-sdk-pom-2.x.x.xml

rdediana · ‎06-20-2017

yes. it was successful.

NOTE: for what it's worth, there is a typo in the guide; which initially caused it to fail. the version and -pom are reversed.

src/main/resources/context-service-sdk-pom-2.x.x.xml

>> actual SDK File name structure: context-service-sdk-2.0.1-pom.xml

mvn install:install-file -Dfile=src/main/resources/context-service-sdk-2.x.x.jar -DgroupId=com.cisco.thunderhead -DartifactId=context-service-sdk -Dversion=2.x.x -Dpackaging=jar -DpomFile=src/main/resources/context-service-sdk-pom-2.x.x.xml

actual results:

RDEDIANA-M-H1S6:cs-example regandediana$ sudo mvn install:install-file -Dfile=src/main/resources/context-service-sdk-2.0.1.jar -DgroupId=com.cisco.thunderhead -DartifactId=context-service-sdk -Dversion=2.0.1 -Dpackaging=jar -DpomFile=src/main/resources/context-service-sdk-2.0.1-pom.xml

RDEDIANA-M-H1S6:cs-example regandediana$

it is after this step where the error is first seen: Step 13:

when copying the following to the pom.xml file (in the project directory)

<groupId>com.cisco.thunderhead</groupId>

<artifactId>context-service-sdk</artifactId>

</dependency>

<groupId>commons-logging</groupId>

<artifactId>commons-logging</artifactId>

</dependency>

</dependencies>

rdediana · ‎06-21-2017

i was able use a temporary solution to resolve the pom.xml file by adding the <systemPath> element to explicitly specific the SDK jar.

<groupId>com.cisco.thunderhead</groupId>

<artifactId>context-service-sdk</artifactId>

<systemPath>${basedir}/src/main/resources/context-service-sdk-2.0.1.jar</systemPath>

</dependency>

As suggested, this did resolve the issue in the pom.xml file, however, it does indicate that maven or the complier is not able to locate the SDK dependencies. i did review the system path and variables to ensure they are referencing the correct locations

M2_HOME=/Users/regandediana/apache-maven/apache-maven-3.5.0

JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home

PATH=$PATH:$JAVA_HOME/bin:$M2_HOME/bin

echo $PATH

...<abreviate>...:/Library/Java/JavaVirtualMachines/jdk1.8.0_131.jdk/Contents/Home/bin:/Users/regandediana/apache-maven/apache-maven-3.5.0/bin

unfortunately, this issue is still persistent; after creating the Register.java class in the tutorial step Register with Context Service the compiler is not able to resolve the SDK artifacts.

any suggestions on how to properly set dependency references for the project? or how to resolve the issues?

thanks for you support.

Regan

rdediana · ‎06-21-2017

i believe if found a temporary solution. in IntelliJ >Program Structure > Modules.

this configuration tool illustrates the issue. i was able to add an external Jar file (cs-sdk) and resolved the reference issues in the Register.java class.

however, these are workarounds to a larger issue. any guidance to properly resolved would be greatly appreciated.

tdippel · ‎06-21-2017

I see that you incorrectly entered the mvn install command from step 12 first before entering it correctly. I'm wondering if that somehow is causing your problems. I think it would be beneficial to delete your ~/.m2 directory and then re-enter the mvn install command from step 12. Once you do that, please verify that the 2.0.1 sdk jar and pom files have been successfully installed in the correct location: ~/.m2/repository/com/cisco/thunderhead/context-service-sdk/2.0.1. Once that has been done, right click on the root of your project in intellij and select Maven > Reimport. You should see the 2.0.1 sdk appear in your external dependencies.

Still Same issue.

Hi Christopher.

yes. that seems to point something i've recently noticed.

to you point. when i issue the maven install it is installing files to /var/root/.m2 path rather than /users/regandediana/.m2

RDEDIANA-M-H1S6:cs-example-project regandediana$ sudo mvn install:install-file -Dfile=src/main/resources/context-service-sdk-2.0.1.jar -DgroupId=com.cisco.thunderhead -DartifactId=context-service-sdk -Dversion=2.0.1 -Dpackaging=jar -DpomFile=src/main/resources/context-service-sdk-2.0.1-pom.xml

context-service-sdk-2.0.1.jar context-service-sdk-2.0.1.pom

RDEDIANA-M-H1S6:2.0.1 regandediana$

one thing i did notice was that the jar and pom sdk files and .lastUpdated appended to the end. this was causing an error when trying to reference them in the pom.xml dependency configuration. when i removed the .lastUpdated these files were properly discovered.

these issue may be related....

i'll try the maven install WITHOUT sudo. however, i suspect since mv install is trying to place the files in var/root ill be prompted once again.

trying now and will update with the results.

thanks again.

rdediana · ‎06-23-2017

ok.

yes. removing sudo did change the destination .m2 repository location.

i'm still getting some errors. however, this is most likely a result of my tinkering around the Intelligj IDE configuration attributes. current issue is:

Exception in thread "main" java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory

at com.cisco.thunderhead.plugin.ConnectorFactory.<clinit>(ConnectorFactory.java:65)

at Register.main(Register.java:8)

at java.lang.ClassLoader.loadClass(ClassLoader.java:357)

... 2 more

Process finished with exit code 1

will rebuild the project again with mv install change; hopefully will resolve the existing issue. crossing fingers.

rdediana · ‎06-23-2017

thanks Christopher. that was it.

using sudo was putting the sdk in the wrong repository.

cheers.

jemuller · ‎06-23-2017

FYI, using sudo is generally BAD when _using_ build tools. Unless something explicitly says to use sudo, you should not.

tweissin · ‎06-21-2017

Hi,

Not sure if you still need help, but if so, can you please try following the README located here?

rdediana · ‎06-21-2017

Thomas. thanks. i'll give that a shot.
