maven cannot find symbol class EJBClientResult
My codes has these compile errors:
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile
(default-compile) on project proj2-war: Compilation failure: Compilation
failure:
[ERROR]
/C:/proj2/proj2-parent/proj2-war/src/main/java/com/mypack/web/common/MyClass.java:[220,340]
cannot find symbol
[ERROR] symbol: class EJBClientResult
[ERROR] location: package mypack.ejb.myproj2
when running
cd C:\proj2\proj2-parent
mvn clean compile
The missing EJBClientResult class is in the mypack.common-2021.03.jar file.
Another similar project which use the same jar file compile successfully.
cd C:\proj1\proj1-parent
mvn clean compile
so the same jar file is present in my maven local repository and maven is
setup properly.
I had done a "mvn clean install" for both projects.
To debug, run
mvn -X clean compile
proj1-parent output:
[DEBUG] com.mypack:mypack.common:jar:2021.03:compile

cannot find symbol
[ERROR] symbol: class EJBClientResult
[ERROR] location: package mypack.ejb.myproj2
Both projects have the same dependency in the pom.xml:
<dependency>
<groupId>com.mypack</groupId>
<artifactId>mypack.common</artifactId>
<version>2021.03</version>
</dependency>
How to fix this compile error?
Please help.
Thanks.

Yes, this is an old company project.
This is an internal company artifactory.
We are converting from Ant to maven.
The EJBClientResult.java is defined in the mypack.common-2021.03.jar.
One project find this jar so compile with maven successfully.
Another project do not find this jar so compile with an error in maven.
The search for EJBClientResult.java within both structures ( projects):
import com.mypack.EJBClientResult;
//...
ArrayList<EJBClientResult> list = ejbResp.getEJBClientResult();
//...
`mvn clean verify -DskipTests` compile with the same error "cannot find
symbol : class EJBClientResult".

Re: maven cannot find symbol class EJBClientResult

Is this an old company project?
As maven-compiler-plugin is showing as v3.5.1 and that was released in Feb
2016.
Also the group id com.mypack is not in maven central so probably in an
internal company nexus or artifactory.
So you might need to search for someone who previous built it.
If you search for EJBClientResult.java within your structure do you find it?
Does `mvn clean verify -DskipTests` work? as it might be it's within a
module of your parent project.
