使用 maven 编译时如何使用 class 文件而不是 java 文件

Question

We received an updated .class file but not the .java file for a project. How can I ensure this new class file is used, and placed in the right directory, in the compiling of our maven pom without affecting the project?

Answer 1

Getting extracted class files is highly unusual. Normally, you get a jar and use it as dependency. In the case you have such class files, I would manually bundle them into a jar file and upload them to your Maven repository with appropriate coordinates (groupId, artifactId, version). Then you can reference them as dependency in your pom.xml .

Answer 2

Not sure if this is the best method, but i was able to accomplish using this class file as a replacement for.java and no.jar file being provided by adding this resource argument to the maven pom file.

<resource>
    <directory>${project.basedir}/src/main/java/com/action/helper</directory>
    <targetPath>${project.build.directory}/classes/com/action/helper</targetPath>
    <excludes>
        <exclude>**/*.java</exclude>
    </excludes>
</resource>
