How to add JAR dependency in java azure functions

Is there a way to add third-party banks to Azure features using JAVA. I would need the json-simple jar and json-databind jars to be available to the function at runtime. Right now, my code throws a runtime exception (ClassNotFound Exception), because the function cannot reference the jar at runtime because it is not available.

I tried using maven-shade-plugin. He creates an executable bank, including external banks, but the deployment still occupies the original bank.

Please offer.

Thank.

I had the same problem and I figured out how to arrange a solution.

, Maven .

<project_root_path> , .

maven, maven-assembly-plugin <project_root_path>/pom.xml <build><plugins>...</plugins></build>:

<plugin>
   <artifactId>maven-assembly-plugin</artifactId>
   <configuration>
      <outputDirectory>${project.build.directory}/azure-functions/${functionAppName}</outputDirectory>
      <appendAssemblyId>false</appendAssemblyId>
      <descriptorRefs>
         <descriptorRef>jar-with-dependencies</descriptorRef>
      </descriptorRefs>
      <archive />
   </configuration>
   <executions>
      <execution>
         <id>make-assembly</id>
         <phase>package</phase>
         <goals>
            <goal>assembly</goal>
         </goals>
      </execution>
   </executions>
</plugin>

Azure Function mvn clean compile package jar <project_root_path>/target/<project_name>.jar, , <dependencies></dependencies> pom.xml.

1: pom.xml, <project_name> <artifactId>_<version>.jar.

2: <appendAssemblyId>false</appendAssemblyId> , <project_name> <artifactId>_<version>-<descriptorRef>.jar. .

, <project_root_path>/target/<project_name>.jar, <project_root_path>/target/azure-functions/<azure_function_name>/, <azure_function_name> - , , .

  • Azure : mvn azure-functions:run
