尝试使用 maven 编译 google 闭包编译器时出错

Question

我正在尝试按照此处的说明编译闭包编译器：

https://github.com/google/closure-compiler

javac -version
javac 1.8.0_232
mvn --version
Apache Maven 3.3.9
Maven home: /usr/share/maven
Java version: 1.8.0_232, vendor: Private Build
Java home: /usr/lib/jvm/java-8-openjdk-amd64/jre
Default locale: en_US, platform encoding: ANSI_X3.4-1968
OS name: "linux", version: "3.10.0-1062.7.1.el7.x86_64", arch: "amd64", family: "unix"

当我执行时：mvn -DskipTests -pl externs/pom.xml，pom-main.xml，pom-main-shaded.xml

这发生在 Ubuntu 16.04.2 LTS 上，但我在 centos 7 上遇到了同样的问题。

有人可以解释一下发生了什么吗？

更新：

我修改了pom.xml并删除了弃用

<compilerArgument>-Xlint:unchecked,deprecation,fallthrough,finally</compilerArgument>

现在，构建失败并显示：

Answer 1

不知道这是否是同一个问题，但我在 Ubuntu 18.04 中也有类似的东西。事实证明，我只安装了JRE，而不是JDK。运行sudo apt install openjdk-8-jdk编译后，没问题。

Answer 2

这是我在 maven 中使用的插件，用于缩小项目的 Javascript 部分。它缩小所有.js文件并在构建阶段覆盖它们。我希望这会有所帮助
