如何在 jenkins 插件中包含针对 JDK 1.8 的依赖项？

Question

我已经按照 official tutorial 创建 Jenkins 插件：我已经运行 mvn -U org.jenkins-ci.tools:maven-hpi-plugin:create 来生成初始 POM

然后我添加了番石榴作为依赖项。

但是，当我执行mvn package 时，我得到：

[INFO] --- maven-enforcer-plugin:1.4.2.jenkins-1:enforce (display-info) @ flaky-tests ---
[INFO] Restricted to JDK 1.7 yet com.google.guava:guava:jar:22.0:compile contains com/google/common/annotations/Beta.class targeted to JDK 1.8
...
[WARNING] Rule 2: org.apache.maven.plugins.enforcer.EnforceBytecodeVersion failed with message:
Found Banned Dependency: com.google.guava:guava:jar:22.0
Use 'mvn dependency:tree' to locate the source of the banned dependencies.

这是我的完整 POM：

在 POM 中添加以下属性就足够了：

<java.level>8</java.level>
