Maven Usage Instructions

To use the forbidden API checker in Maven, use the following template to include the plugin:

<properties>
  <!-- 
   It is recommended to set the compiler version globally,
   as the compiler plugin and the forbidden API checker both
   use this version
  -->
  <maven.compiler.target>1.7</maven.compiler.target>
</properties>

<build>
  <plugins>
    <plugin>
      <groupId>de.thetaphi</groupId>
      <artifactId>forbiddenapis</artifactId>
      <version>3.6</version>
      <configuration>
        <!--
          if the used Java version is too new,
          don't fail, just do nothing:
        -->
        <failOnUnsupportedJava>false</failOnUnsupportedJava>
        <bundledSignatures>
          <!--
            This will automatically choose the right
            signatures based on 'maven.compiler.target':
          -->
          <bundledSignature>jdk-unsafe</bundledSignature>
          <bundledSignature>jdk-deprecated</bundledSignature>
          <!-- disallow undocumented classes like sun.misc.Unsafe: -->
          <bundledSignature>jdk-non-portable</bundledSignature>
          <!-- don't allow unsafe reflective access: -->
          <bundledSignature>jdk-reflection</bundledSignature>
        </bundledSignatures>
        <signaturesFiles>
          <signaturesFile>./rel/path/to/signatures.txt</signaturesFile>
        </signaturesFiles>
      </configuration>
      <executions>
        <execution>
          <goals>
            <goal>check</goal>
            <goal>testCheck</goal>
          </goals>
        </execution>
      </executions>
    </plugin>
  </plugins>
  <!-- more build settings here... -->
</build>

The possible <bundledSignatures> can be found on a separate page. You can also give your own signatures in separate files from your project directory.

Since version 1.2 the goal was renamed to "check" and "testCheck" (to check the test classes) was added. Since version 2.0, the plugin runs by default in the verify lifecycle phase. Of course, you can assign any other phase, like the previous process-classes / process-test-classes.

The detailed documentation (based on nightly snapshots) can be found here: https://jenkins.thetaphi.de/job/Forbidden-APIs/javadoc/

Suppression of specific classes

Suppression of generated classes

You can suppress generated classes by using an annotation. Those usually have one of the three following annotations:

<build>
  <plugins>
    <plugin>
      <groupId>de.thetaphi</groupId>
      <artifactId>forbiddenapis</artifactId>
      <configuration>
        <suppressAnnotations>
          <!-- Java <= 8 -->
          <suppressAnnotation>javax.processing.Generated</suppressAnnotation>
          <!-- Java 9+ via javax.annotation-pi -->
          <suppressAnnotation>javax.annotation.processing.Generated</suppressAnnotation>
          <!-- immutables.org -->
          <suppressAnnotation>org.immutables.value.Generated</suppressAnnotation>
          <!-- Project Lombok -->
          <suppressAnnotation>api.lombok.Generated</suppressAnnotation>
        </suppressAnnotations>
      </configuration>
    </plugin>
  </plugins>
</build>
