java - Maven Test Scope -

if have 1 project of mine myproject1 has following depenedencies:

        <!-- logging -->         <dependency>             <groupid>org.slf4j</groupid>             <artifactid>slf4j-api</artifactid>             <version>1.7.6</version>         </dependency>         <dependency>             <groupid>ch.qos.logback</groupid>             <artifactid>logback-core</artifactid>             <version>1.1.1</version>             <scope>test</scope>         </dependency>         <dependency>             <groupid>ch.qos.logback</groupid>             <artifactid>logback-classic</artifactid>             <version>1.1.1</version>             <scope>test</scope>         </dependency> 

and include myproject1 in myproject2 so:

    <dependency>         <groupid>com.mydomain</groupid>         <artifactid>myproject1</artifactid>         <version>1.0</version>     </dependency>     <!-- android logging-->     <dependency>         <groupid>com.github.tony19</groupid>         <artifactid>logback-android-core</artifactid>         <version>1.1.1-2</version>     </dependency>     <dependency>         <groupid>com.github.tony19</groupid>         <artifactid>logback-android-classic</artifactid>         <version>1.1.1-2</version>     </dependency> 

i still seeing logback classes being included in myproject2. understanding test scope should prevent jars bleeding parent projects. misunderstanding something? running compilation issues parent project relies on logback-android , have multiple classes same name e.g. ch.qos.logback.classic.asyncappender.

you can exclude transitive dependencies myproject1 , have 2 options here.

optional dependency. mark logback-core in myproject1 optional:

<dependency>     <groupid>ch.qos.logback</groupid>     <artifactid>logback-core</artifactid>     <version>1.1.1</version>     <scope>test</scope>     <optional>true</optional> </dependency> 

excluded dependency. exclude logback-core when including myproject1:

<dependency>     <groupid>com.mydomain</groupid>     <artifactid>myproject1</artifactid>     <version>1.0</version>     <exclusions>         <exclusion>             <groupid>ch.qos.logback</groupid>             <artifactid>logback-core</artifactid>         </exclusion>     </exclusions> </dependency> 

also think if run build tests off (-dmaven.test.skip=true) logback-core not included anyway.

run mvn dependency:tree see origin of dependencies , scope.
