Question

我们正在尝试在我们的Vaadin项目中初始化一个hibernate数据库，但它会引发以下错误。我们已经搜索了几天，但到目前为止还没有解决方案，我们的想法也没有。希望有人可以提供帮助。我们正在使用NetBeans。

Answer 1

我在 .pom 文件中看到了问题。 “ maven install ”因 .pom 文件失败，但在以下更新后，“ maven install ”工作正常;

只需删除下面的依赖项，maven install就失败了;

    <dependency>
        <groupId>org.slf4j</groupId>
        <artifactId>slf4j-jdk14</artifactId>
        <version>1.7.13</version>
        <exclusions>
            <exclusion>
                <groupId>org.slf4j</groupId>
                <artifactId>slf4j-api</artifactId>
            </exclusion>
        </exclusions>
    </dependency>

只需更新您的 .pom 文件（或在下方复制/粘贴更新的 .pom ），然后运行maven clean和{{1通过命令行在项目目录上。

我刚刚运行你的pom文件而没有依赖 slf4j-api ，版本 1.7.13 并且maven install成功运行[ BUILD SUCCESS

maven install

Answer 2

好吧，在我的情况下，我遇到了同样的异常，但是原因却完全不同。

我正在使用最新版本的1.3.0-alpha4

加载所有依赖项

就我而言，必须使用较旧的版本1.2.3

以下是我的工作依赖-

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
    <scope>test</scope>
</dependency>

希望这对您有帮助。
