Maven Surefire 与 JUnit 5 隐藏堆栈跟踪

Question

如果我这样做：

mvn -X \
     -Dtest=MojoIntegrationTest \
     -Dsurefire.trimStackTrace=false \
     -Dsurefire.useFile=false  \
     clean test

@BeforeEach
public void setUp() {
    stuff();
}

@Test
public void testMyApp() {
    doApp();
}

和 stuff() 或 doApp() 以某种方式爆炸，我没有得到完整的堆栈跟踪，无论是在控制台还是在文件中。 JUnit5 或 Maven 隐藏了它们：

除了这样做：

@BeforeEach
public void setUp() {
    try {
        stuff();
    } catch (Exception e) {
        e.printStackTrace();
        throw e;
    }
 }

我真的不喜欢，我怎样才能得到堆栈跟踪？

谢谢。

[更新 2]：最初这只是影响我的 @BeforeEach 例程，但现在我正在编写测试，我意识到它实际上无处不在，即 mvn junit5 隐藏了我所有的堆栈跟踪。

您必须使用 -DtrimStackTrace=false 而不是 -Dsurefire.trimStackTrace=false:

mvn clean test -DtrimStackTrace=false
