unable to run spring boot app it exits saying An attempt was made to call a method that does not exist

Question

Whenever I try to run my spring boot application it runs until it finishes creating the entities inside the database and then it exits with the error

I tried to exclude Gson from Jcloudes, I tried to add Gson dependency explicitly, I tried to shade it in the on the apache jcloude, I tried all the solutions I could get by searching the web, and nothing worked next is the maven pom.xml of the parent module:

APPLICATION FAILED TO START

---

Description:

An attempt was made to call a method that does not exist. The attempt was made from the following location:

org.jclouds.json.internal.DeserializationConstructorAndReflectiveTypeAdapterFactory.<init>(DeserializationConstructorAndReflectiveTypeAdapterFactory.java:117)

The following method did not exist:

com.google.gson.internal.bind.ReflectiveTypeAdapterFactory.<init>(Lcom/google/gson/internal/ConstructorConstructor;Lcom/google/gson/FieldNamingStrategy;Lcom/google/gson/internal/Excluder;)V

The method's class, com.google.gson.internal.bind.ReflectiveTypeAdapterFactory, is available from the following locations:

jar:file:/D:/JavaEE_development/JavaEEMvnRepository/.m2/repository/com/google/code/gson/gson/2.8.5/gson-2.8.5.jar!/com/google/gson/internal/bind/ReflectiveTypeAdapterFactory.class

It was loaded from the following location:

file:/D:/JavaEE_development/JavaEEMvnRepository/.m2/repository/com/google/code/gson/gson/2.8.5/gson-2.8.5.jar

Action:

Correct the classpath of your application so that it contains a single, compatible version of com.google.gson.internal.bind.ReflectiveTypeAdapterFactory

Process finished with exit code 1

Answer 1

For those who face the same problem with jCloud, the problem is when you use Gson or guava or any library the included in jcloud dependency, you may use a particular version but jcloud use another version of the same libraries you use in your classpath which can cause class loading conflicts due to duplicate classes on the classpath. in my case, the conflicts were due to using google-Gson and google-guava

libraries in my code a new version, which also came with jcloud as an old version. The solution is to create a shaded jar file of the jcloud library in which you shade all the duplicated libraries you use in your classPath I did this by creating a maven project which includes the following pom:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>jcloud.eagleboard</groupId>
  <artifactId>jcloud-shaded</artifactId>
  <version>1.0-SNAPSHOT</version>

  <properties>
    <jclouds.version>2.1.2</jclouds.version>
  </properties>

      <artifactId>jclouds-core</artifactId>
      <version>${jclouds.version}</version>
    </dependency>
    <dependency>
      <groupId>org.apache.jclouds</groupId>
      <artifactId>jclouds-blobstore</artifactId>

      <groupId>org.apache.jclouds.api</groupId>

      <version>${jclouds.version}</version>
    </dependency>

    <dependency>
      <groupId>org.apache.jclouds.provider</groupId>
      <artifactId>aws-s3</artifactId>
      <version>${jclouds.version}</version>
    </dependency>
  </dependencies>

  <build>
    <plugins>
      <plugin>

        <artifactId>maven-shade-plugin</artifactId>

        <executions>
          <execution>
            <phase>package</phase>
            <goals>
              <goal>shade</goal>
            </goals>
            <configuration>
              <relocations>
                <relocation>

              </relocations>
              <transformers>
                <transformer
                  implementation="org.apache.maven.plugins.shade.resource.ServicesResourceTransformer"/>
              </transformers>
            </configuration>
          </execution>
        </executions>
      </plugin>
    </plugins>
  </build>
</project>

Then I packaged it using the following command in the terminal:

mvn package

a file named jcloud-shaded-1.0-SNAPSHOT is then created inside the target directory, the name depends on the way you structure your shaded pom file. copy that file to your project's home directory for example inside a directory called local-maven-repo.

then create the local repository and add to your project a dependency to the resulted jar file and the repository you created with the jar file inside

mvn install:install-file -Dfile=./local-maven-repo/jcloud-shaded-1.0-SNAPSHOT.jar -DgroupId=jcloud.eagleboard -DartifactId=jcloud-shaded -Dversion=1.0-SNAPSHOT -Dpackaging=jar

and in my project pom file included the dependency to that local shaded jar:

<repositories>
    <repository>
      <id>local-maven-repo</id>
      <url>file://${project.basedir}/local-maven-repo</url>
    </repository>
</repositories>

... ...

<dependency>
      <groupId>jcloud.eagleboard</groupId>
      <artifactId>jcloud-shaded</artifactId>
      <version>1.0-SNAPSHOT</version>
    </dependency>

Answer 2

Try upgrading to jclouds 2.2.0-SNAPSHOT. This includes fixes for JCLOUDS-1166 and JCLOUDS-1500 which will likely fix your symptoms.
