I have 2 projects, A and B. B is a lib project and A reference to B.
When I add new function to B, it's ok to run mvn install
on B, but it failed on mvn install
on A due to can not find the symbol from new B.
I'm sure I did install correctly on project B, but why A still failed to compile and install?
This is A's pom.xml:
<dependency>
<groupId>A and B's group</groupId>
<artifactId>B</artifactId>
<scope>provided</scope>
</dependency>
any clue? Thanks

I would suggest to create a multi-module build like the following:
+-- root
+-- pom.xml
+-- module-A
+-- module-B
In the root pom you need to define the modules like this and define the packaging to pom.
<modules>
<module>module-A</module>
<module>module-B</module>
</modules>
Furthermore you can define a dependency of module-A to module -B simply by:
<project ..
<parent>
<groupId>project.parent</groupId>
<artifactId>parent</artifactId>
<version>1.0-SNAPSHOT</version>
</parent>
<artifactId>module-A</artifactId>
<dependencies>
<dependency>
<groupId>${project.groupId}</groupId>
<artifactId>module-B</artifactId>
<version>${project.version}</version>
</dependency>
..
</dependencies>
..
</project>
With this setup you can simply build all modules from the root folder just by:
mvn clean package
or you can import that structure into Eclipse (m2e installed?) or any other IDE like IntelliJ or Netbeans.

You can include the <version>
element in the project's as well as dependency's declaration.
${build.version}
Module A's pom.xml
:
<groupId>A & B's Group ID</groupId>
<artifactId>A</artifactId>
<version>${build.version}</version>
<dependencies>
<dependency>
<groupId>A & B's Group ID</groupId>
<artifactId>B</artifactId>
<version>${build.version}</version>
<type>war</type>
<scope>provided</scope>
</dependency>
...
So, whenever Project B is built and installed, the dependency will be available in the local maven repository for that particular version and will be picked by Project A

Try mvn clean install
to do a totally fresh build of A, or mvn -U install
to force Maven to look for updated snapshots. It sounds like your environment is still using the older JAR. It's hard to tell what your setup is from this description -- sounds like you're correctly installing B to your local repository, but I'm not sure if your IDE might be trying to be 'helpful' as well.
