Maven build success with several warnings while downloading dependency from remote repository BitBucket

Question

I would like to can download a dependency present on BitBucket remote repository from an another project Maven. To reply the case I've created a remote repository like this: https://bitbucket.org/[user]/mvn-repo

Then, I've created two projects Maven: test and test2 (The project test has only a static method of testing).

Here's test project's POM:

<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">

                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
</project>

while here's test2 project's POM:

<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">

        </dependency>
    </dependencies>

    </properties>

    <repositories>

        </repository>
        <repository>
            <id>Maven Central</id>
            <url>http://repo.apache.maven.org/maven2/</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>
</project>

I've taken the following steps:

Installed the project test on the local repository Maven with command: mvn clean install -DcreateChecksum=true
Copied the project test (as such as org/test/test) from local repository Maven to the folder /git-repo/mvn-repo, then I've pushed on BitBucket remote repository.
Removed folders org/test/test from local repository Maven.
Executed command: mvn clean install -DcreateChecksum=true under the project folder test2.

This is the result

Maven build shows several warnings even if it returns a build success. The file test-0.0.1-SNAPSHOT.jar result be corrupted. How can I resolve the problem?
Thanks for your help in advance.

UPDATE

I've changed the test project's POM for attempting to execute the command mvn deploy -X, however Maven returns the same result:

You need to pass up this "user" on url via maven property. When maven try to download it creates a corrupted version in your .m2 repository. Try deleting this parent dependency from .m2 folder and build again. — DaviM, Sep 20 '18 at 01:50

try this on your pom:

<properties>
    <bitBucketUser>${user}</bitBucketUser>
</properties>

<repositories>
    <repository>
        <id>internal repository</id>
        <url>https://bitbucket.org/${bitBucketUser}/mvn-repo/raw/master/</url>
    </repository>
    <repository>
        <id>Maven Central</id>
        <url>http://repo.apache.maven.org/maven2/</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

and then execute your clean install mvn clean install -Duser=yourBitBucketUser

I don't figure out what you want to say. Perhaps there was a misunderstanding. Actually, what you see like **[user]** is BitBucket's my user. – user2863754 Sep 20 '18 at 20:38
I know. I mean, don't you need to pass this user as parameter/property? Or you just hid it? Sorry if I misunderstand you. In case you hid it, looks like your dependency is corrupted. Try to delete from your .m2 repository and download again. – DaviM Sep 21 '18 at 02:30
What i do is to delete the project **test** every time from my .m2 repository. Then I go to the project **test2** and execute the commands `mvn clean install` (Here it should download my dependency **test** from BitBucket remote repository and install test and test2 into the local folder .m2, but It keep giving errors). When you say "looks like your dependency is corrupted" you're right. In fact, happens when i only download my dependency from remote repository. – user2863754 Sep 21 '18 at 11:40
Maybe your dependency in your bitbucket remote repo might be corrupted. – DaviM Sep 21 '18 at 16:30
I've checked my test-0.0.1-SNAPSHOT.jar on remote repo and It doesn't result corrupted. What's your solution to you? – user2863754 Sep 21 '18 at 20:34

Maven build success with several warnings while downloading dependency from remote repository BitBucket
