Question

我目前正在IntelliJ IDE中开发Java 8应用程序。我遇到了JetBrains annotations，我开始像这样使用它们：

public class ClassA {
    public ClassA(@NotNull ClassB classB, @NotNull ClassC classC) {
        ...
    }
}

和测试文件如下：

public class ClassATest {
    @Test(expected = IllegalArgumentException.class)
    public void testConstructorNull1() {
        new ClassA(null, null);
    }
}

只要我从IDE注释运行应用程序/测试工作，但是当我运行例如来自命令行的mvn tests，在测试NullPointerException参数时，我得到了很多IllegalArgumentException而不是预期的null。似乎注释被忽略了。

我认为问题出现在pom.xml的错误配置中，如下所示：

如果添加maven插件，它将起作用：

<pluginRepositories>
    <pluginRepository>
        <id>repository.jetbrains.com</id>
        <name>repository.jetbrains.com-all</name>
        <url>http://repository.jetbrains.com/all</url>
        <snapshots>
            <enabled>true</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>

<build>
    <plugins>
        <plugin>
            <groupId>com.intellij</groupId>
            <artifactId>notnull-instrumenter-maven-plugin</artifactId>
            <version>1.0-SNAPSHOT</version>
            <executions>
                <execution>
                    <goals>
                        <goal>instrument</goal>
                        <goal>tests-instrument</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

org.jetbrains：手动运行Maven测试时，注释不起作用
