問題描述
無法在 JDK7 上運行 Maven 3.6.3 (Can't run Maven 3.6.3 on JDK7)
└─❯ mvn ‑version
Apache Maven 3.6.3
Maven home: /usr/share/maven
Java version: 1.7.0_80, vendor: Oracle Corporation, runtime: /home/jqno/.jabba/jdk/1.7.80‑oracle/jre
Default locale: en_US, platform encoding: UTF‑8

看起來，Maven 嘗試加載為 JDK8 編譯的類，因為它抱怨 52.0 的類版本不受支持。但是我找不到哪個類，或者為什麼 Maven 首先嘗試加載它。我在 Google 上找到的所有內容似乎都無關。
發生了什麼事？我該如何解決這個問題？
更新我已經解壓了 /usr/share/maven/lib/guice‑no‑aop.jar 文件並運行 javap ‑verbose com.google.inject.Module，它確實有 52.0 版本。我不知道該文件是如何到達那裡的（我假設它是由 apt install maven 安裝的，但我不確定）。

方法 1:
The problem here is that Ubuntu has repackaged Maven which in result produces the issue.
As shown here if you check the version via:
mvn ‑‑version
Apache Maven 3.6.3
Maven home: /usr/share/maven
Java version: 1.7.0_80, vendor: Oracle Corporation, runtime: /home/jqno/.jabba/jdk/1.7.80‑oracle/jre
Default locale: en_US, platform encoding: UTF‑8
OS name: "linux", version: "5.11.0‑16‑generic", arch: "amd64", family: "unix"
This shows that you are NOT using Apache Maven.
If you do that on plain command line and install Apache Maven via https://maven.apache.org/download.cgi you will get an output like this:
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /Users/XXX/tools/maven
Java version: 1.7.0_302, vendor: Azul Systems, Inc., runtime: /Users/khmarbaise/.sdkman/candidates/java/7.0.302‑zulu/zulu‑7.jdk/Contents/Home/jre
Default locale: en_GB, platform encoding: UTF‑8
OS name: "mac os x", version: "10.14.6", arch: "x86_64", family: "mac"
The most important part is the first line:
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
This is Apache Maven.
Second if you take careful look into the error output:

You see that this is in particular different to the given output you have where only file:/usr/share/maven/lib/guice‑4.2.1‑no_aop.jar apart from the missing version number of the other artifacts.
That means the problem is based on the usage of Ubuntu Maven and NOT using Apache Maven which is compatible with JDK 7 where as the repackaged version of Ubuntu is simply not.
The simplest solution is to remove the ubuntu Package of Maven and install the original Apache Maven https://maven.apache.org/download.cgi then the build with JDK 7 will work. (Download and check the checksums etc.)
Also you can download the Apache Maven and check the checksums of files against the ones of your distro (/usr/share/maven/lib/) I bet that all files are different.
The issue is based on the idea of distros to repackage Application (for example Maven) with their dependencies which are on their system which in reality means you have different versions of dependencies which results in such issues.
