我有一个使用 maven、spring-boot 并连接到 postresql 数据库的简单项目。当我运行 mvn clean install 时，一切都运行良好，甚至是测试。（我正在用 java 10 编译它）然后我添加一个 module-info.java 将它变成一个 java9 模块。现在，如果我构建它并且我没有 -DskipTests，我会收到以下错误：
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-surefire-plugin:2.22.1:test (default-test) on project birdtree-model-dao: There are test failures.

并且 surefire-reports 文件包含：
# Created at 2019-05-01T00:58:57.663
Error: Could not find or load main class practice\Mentoring
# Created at 2019-05-01T00:58:57.663
Caused by: java.lang.ClassNotFoundException: practice\Mentoring
（听起来有点像问题是文件路径中的空间，对吗？但如果是，我在哪里更正？）
所以，我认为这一定是模块信息的错，因为这是唯一改变的事情。我一直在纠结要放什么。自动生成的一个 Eclipse 似乎是错误的，例如因为它包含测试依赖项，这给了我其他错误。所以我尝试了一下，它目前看起来像这样：
module birdtreeModelDao {
exports mjl.familytree.birdtree;
//requires junit; //eclipse adds this. But I think test dependencies don't belong here, right?
requires spring.boot;
requires spring.boot.autoconfigure; //included this externally by creating new library
//requires spring.boot.test; //eclipse adds this. But it just gives me other errors. And again, it's a test dependency, so surely it shouldn't be here.
requires spring.context;
}
这是我的pom：

知道是什么导致了错误吗？
