Maven tycho-surefire-plugin 失败，代码为 return 13
Maven tycho-surefire-plugin fails with return code 13
我有一个 OSGI 包，现在想为它创建一个测试包。由于现有的包使用 Tycho，我还想使用 tycho-surefire-plugin 来测试 Eclipse/Tycho-way。
据我了解，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相应包。
所以我使用以下 pom 创建了一个新包 "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>
我还创建了 tycho/OSGI-projects 的其他标准文件
META-INF/MANIFEST.MF
Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: %Bundle-Name
Bundle-SymbolicName: xyz
Bundle-Version: 0.0.1.qualifier
Bundle-RequiredExecutionEnvironment: JavaSE-1.7
Fragment-Host: zyx
Import-Package: org.junit;version="4.11.0"
Bundle-ActivationPolicy: lazy
build.properties
output.. = bin/
source.. = src/
bin.includes = META-INF/,\
OSGI-INF/,\
.
和OSGI-INF/l10n/bundle.properties
# META-INF/MANIFEST.MF
Bundle-Name=XYZ Tests
然后我写了一个 "test-case" 因为我首先想检查我的 eclipse-test-plugin 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 package为目标时，一切都编译和打包没有错误。然后我 运行 mvn integration-test 作为目标（这是 tycho-surefire 开始工作的部分）。我收到一条错误消息，其中没有提供对我有用的信息：

"xyz: Hello/Goodbye World" 消息是当我想测试 starts/stops 包时打印的消息。这意味着，当包启动时我的配置似乎没问题，但在它之后立即发生错误。不幸的是，查看日志文件也没有发现任何有用的信息：

所以我知道发生了空指针异常，但是我不知道why/where。
我认为看到隐藏在“... 28 more”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...
我也不完全确定我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。
我终于找到问题的根源了：
我使用的是 tycho v0.21.0，此问题被报告为错误 (https://bugs.eclipse.org/bugs/show_bug.cgi?id=369266)，并已通过 tycho v0.22.0 得到修复。
将 tycho-surefire-plugin 的版本更改为 属性 解决了问题。
