Maven tycho surefire插件失败，返回代码13

我有一个OSGI包，现在想为它创建一个测试包。由于现有的bundle使用了Tycho，我还想通过使用Tycho-surefire插件来测试Eclipse/Tycho

据我所知，测试Eclipse方式意味着每个包都有一个包含所有相关测试用例的对应包

因此，我使用以下pom创建了一个新的捆绑包“xyz.tests”：

    <artifactId>xyz.tests</artifactId>
    <packaging>eclipse-test-plugin</packaging>

    <build>
        <plugins>
            <plugin>
                <groupId>org.eclipse.tycho</groupId>
                <artifactId>tycho-surefire-plugin</artifactId>
                <version>0.21.0</version>
            </plugin>
        </plugins>
    </build>

构建属性

output.. = bin/
source.. = src/
bin.includes = META-INF/,\
           OSGI-INF/,\
           .

# META-INF/MANIFEST.MF
Bundle-Name=XYZ Tests

和OSGI-INF/l10n/bundle.properties

output.. = bin/
source.. = src/
bin.includes = META-INF/,\
           OSGI-INF/,\
           .

# META-INF/MANIFEST.MF
Bundle-Name=XYZ Tests

然后我写了一个“测试用例”，因为我第一次想检查我的eclipse测试插件是否配置正确

package xyz.tests.xyz;

import static org.junit.Assert.assertEquals;
import org.junit.Test;

public class XYZTest {

    @Test
    public void testClasstest() {
        assertEquals("Tests", true, true);
    }
}

当我以运行mvn包为目标时，所有的编译和包都不会出错。然后我以运行mvn集成测试为目标（这是tycho surefire开始工作的部分）。在那里，我收到一条错误消息，它没有为我提供任何有用的信息：

“xyz:Hello/debye World”消息是我想要测试的包启动/停止时打印的消息。这意味着，当bundle启动时，我的配置似乎是正常的，但在启动后立即出现错误。不幸的是，查看日志文件也没有发现任何有用的信息：

    ... 28 more

所以我知道会发生空指针异常，但我不知道为什么/在哪里

我认为看到隐藏在“…28更多”后面的整个错误路径真的很有帮助，但我不知道如何看到它

---

我也不完全确定是否正确配置了所有内容，因为我没有找到有用的教程，并且或多或少地查看了其他eclipse项目的测试代码库。

我终于找到了问题的根源：

我使用的是tycho v0.21.0，该问题被报告为bug（），并通过tycho v0.22.0得到修复

更改tycho surefire插件的version属性解决了此问题
