Question

如果我的测试方法或我的测试调用的EJB使用lambdas，我的Arquillian测试无法运行。测试甚至不足以运行，看起来它在arquillian初始化时失败了。例如，把这个

Stream.of("one", "two", "three").map(String::new);

进入我的测试方法时，在eclipse中作为junit测试执行时会导致以下异常。

我使用的是Arquillian 1.1.8.Final和JBoss shrinkwrap resolver 2.2.0

Answer 1

删除arquillian-suite-extension作为依赖项修复了问题，即使我没有使用它

    <dependency>
        <groupId>org.eu.ingwar.tools</groupId>
        <artifactId>arquillian-suite-extension</artifactId>
        <version>1.1.2</version>
        <scope>test</scope>
    </dependency>

Answer 2

要添加到John Ament的评论，因为它对我来说并不是很明显，而且这个问题仍然存在：

使用arquillian-suite-extension时，您需要在pom.xml中将org.reflections/reflections的版本设置为0.9.9。无论是高于还是低于我的版本。

这是您的pom.xml中所需的条目：

<dependency>
    <groupId>org.reflections</groupId>
    <artifactId>reflections</artifactId>
    <version>0.9.9</version>
</dependency>

当代码具有java 8 lambda表达式时，Arquillian测试不会运行
