Android build works in Eclipse but not with Ant (“already added”)

Question

My Android project uses several git submodules marked as Android Libraries. These submodules all have different uses of the ORMlite Android jars and thus have the ORMlite ja

Answer 1

My problem was that all jars in any ./libs folder were included, not just the ones as specified in my eclipse .classpath. So I had some duplicates laying around there. I just needed to clean up my ./libs. You can find out what ant is all including in its "classpath" by running "ant -v debug", somewhere in the top half of the output.

Answer 2

I solved my problem by creating a third Android project with only the ORMlite JAR in it that the two other projects depended on.

Answer 3

i got the same problem using maven because it correctly added the ormlite-core-jarfile, which contains the packages and classes as the core-jar with a few additional classes.

I added an exclusion and now it works

            <dependency>
                <groupId>com.j256.ormlite</groupId>
                <artifactId>ormlite-android</artifactId>
                <version>4.9</version>
                <exclusions>
                    <exclusion>
                        <groupId>com.j256.ormlite</groupId>
                        <artifactId>ormlite-core</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>

Had the same problem but with android-support-v4.jar — it was used in referenced project library and app project. Here's the solution

Workaround: 1. Remove file android-support-v4.jar from App/libs 2. In Eclipse add jar referenced to ReferencedProjectLibrary/libs/android-support-v4.jar

It works in Eclipse and Ant too ;)
