Understanding the Error
The "More Than One File Found with OS Independent Path META-INF/Dependencies" error typically occurs when there are duplicate files or resources in your project. This can happen when different libraries or modules in your project have the same file path, causing conflicts during the build process.
A common cause of this error is when libraries with overlapping dependencies are included in the same project, leading to duplicated resources in the META-INF folder.
Step by Step Solution
Follow these steps to resolve the "More Than One File Found with OS Independent Path META-INF/Dependencies" error.
Step 1: Identify Conflicting Libraries
The first step is to identify the conflicting libraries or resources in your project. This can be done by reviewing your project's build file (e.g., pom.xml for Maven or build.gradle for Gradle) and looking for any overlapping dependencies.
Step 2: Exclude Duplicate Resources
Once you have identified the conflicting libraries, you can either:
Exclude the duplicate resources from your build process by adding an exclusion rule in your build file. This will prevent the conflicting resources from being included in your project's final build artifact.
For Maven, add the following exclusion rule in your pom.xml:
<dependency>
<groupId>com.example.library</groupId>
<artifactId>library-with-conflict</artifactId>
<version>1.0.0</version>
<exclusions>
<exclusion>
<groupId>META-INF</groupId>
<artifactId>Dependencies</artifactId>
</exclusion>
</exclusions>
</dependency>
For Gradle, add the following exclusion rule in your build.gradle:
implementation ('com.example.library:library-with-conflict:1.0.0') {
exclude group: 'META-INF', module: 'Dependencies'
}
Alternatively, you can remove or replace one of the conflicting libraries with a non-conflicting version, if possible.
Step 3: Clean and Rebuild Your Project
After updating your build file with the appropriate exclusion rules or library changes, clean and rebuild your project to ensure the changes take effect. This can be done using your build tool's clean and build commands, for example:
- For Maven:
mvn clean install - For Gradle:
./gradlew clean build
FAQs
What is the META-INF folder?
The META-INF folder is a standard directory that contains metadata about a Java archive (JAR) file or an Android application. It often includes manifest files, service provider configurations, or other resource files required by libraries or modules in your project.
Why does this error occur?
This error occurs when there are duplicate files or resources with the same OS-independent path (e.g., META-INF/Dependencies) in your project. This can cause conflicts during the build process and prevents the build from completing successfully.
Can I ignore this error?
Ignoring this error is not recommended, as it may lead to unpredictable behavior, crashes, or incorrect functionality in your application. It is essential to resolve the conflict to ensure your application works correctly.
How do I prevent this error from occurring in the future?
To prevent this error from occurring in the future, you should regularly review your project's dependencies and ensure that there are no conflicts between libraries or resources. Additionally, you can use tools like Maven Enforcer Plugin or Gradle Dependency Analysis Plugin to automatically detect and report dependency conflicts in your project.
What if I still get the error after following the steps in this guide?
If you still encounter the "More Than One File Found with OS Independent Path META-INF/Dependencies" error after following the steps in this guide, it is possible that there are additional conflicts in your project. In this case, you may need to review your build file and project configuration to identify and resolve any remaining conflicts.
