Description

Given:

• Create a new route project using spring-boot archetype
• Create `src/main/resources/test.json` with contents:

[{ "fizz": "buzz" }]

• Add the following XML to the `<plugins>` node in `pom.xml`:

<plugin>
  <groupId>org.apache.camel</groupId>
  <artifactId>camel-package-maven-plugin</artifactId>
  <version>3.10.0</version>
  <executions>
    <execution>
      <id>generate</id>
      <goals>
        <goal>generate-component</goal>
      </goals>
      <phase>process-classes</phase>
    </execution>
  </executions>
</plugin>

• Run `mvn package`

Expected:

[INFO] BUILD SUCCESS

Observed:

Notes:

Removing the square brackets avoids the problem. For example, the following `test.json` contents enables a successful build:

{ "fizz": "buzz" }

In addition, renaming the file to `test.txt` avoids the problem.
