Maven tests troubles with SOAP having Java EE 6 dependency

问题

I'm finding troubles when trying to use SOAP in tests in a maven project that has Java EE 6 API as a provided-scoped dependency.

Important facts

1. I'm aware that the API is unusable for testing
2. I know I should import an implementation of any specification if I want to use it
3. SOAP is part of Java SE, not EE
4. SOAP (mock) classes are included in the Maven artifact and I believe they should not
5. This happens in Java EE 6, but those classes have been removed in version 7
6. If I remove the dependency, the tests work fine
7. When using 7.0 version of the API everything works

Exception

POM configuration

<dependencies>
  ...
  <dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
  </dependency>
  ...
</dependencies>

<build>
  ...
  <plugins>
    ...
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.17</version>
      ...
    </plugin>
    ...
  </plugins>
  ...
</build>

Failed solutions

I have tried several solutions (not going to post each one for clarity, but will post them by request):

1. I have tried every single <scope/> in Maven and none disables the library in tests
2. Also, tried excluding the library as a dependency of the plugin
3. Including rj.jar as a system dependency with a higher priority than javaee-api one didn't work either

Unwanted workaround

I got the tests working using 7.0 dependency but this is unacceptable according to policies, so I need to fix this.

回答1:

I got to make it work using the property classpathDependencyExcludes of the maven-surefire-plugin:

<build>
  ...
  <plugins>
    ...
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.17</version>
      ...
      <configuration>
        <classpathDependencyExcludes>
          <classpathDependencyExcludes>javax:javaee-api</classpathDependencyExcludes>
        </classpathDependencyExcludes>
        ...
      </configuration>
      ...
    </plugin>
    ...
  </plugins>
  ...
</build>

I'm going to leave this posted as I believe I'll not be the only one experiencing this at some point.

回答2:

I was running in the same problem as below while running java class. Exception: java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/xml/messaging/URLEndpoint

With Java8 as runtime, I finally included correct version (7.0) and the program started working fine earlier it was taking version 6.

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>7.0</version>
    <scope>provided</scope>
</dependency>
