无法从 Maven 3.5.2 降级到 Maven 3.0.4：没有名称为 "maven30" 的可用公式

Question

我已经使用

卸载了 maven

brew uninstall maven

并尝试使用

再次安装

brew install maven30

但我遇到了这个错误

 brew install maven30
Error: No available formula with the name "maven30" 
==> Searching for a previously deleted formula (in the last month)...
Warning: homebrew/core is shallow clone. To get complete history run:
  git -C "$(brew --repo homebrew/core)" fetch --unshallow

Error: No previously deleted formula found.
==> Searching for similarly named formulae...
==> Searching local taps...
Error: No similarly named formulae found.
==> Searching taps...
==> Searching taps on GitHub...
Error: curl is not executable

然而，当我使用 brew install maven 时，它也被下载并安装了

   brew install maven
==> Downloading https://www.apache.org/dyn/closer.cgi?path=maven/maven-3/3.5.2/b
Already downloaded: /Users/amar/Library/Caches/Homebrew/maven-3.5.2.tar.gz
  /usr/local/Cellar/maven/3.5.2: 104 files, 10.1MB, built in 3 seconds

所以为什么我在 maven30

中得到 curl is not executable

我也试过了

 brew tap homebrew/versions
Warning: homebrew/versions was deprecated. This tap is now empty as all its formulae were migrated.

Answer 1

我从 here 下载了 3.0.4 的 mvn zip 文件，然后执行位于 bin 文件中的 mvn 命令，如下所示

amar@admin:~/Downloads/apache-maven-3.0.4$ tree -L 2

    ├── LICENSE.txt
    ├── NOTICE.txt
    ├── README.txt
    ├── bin
    │   ├── m2.conf
    │   ├── mvn
    │   ├── mvn.bat
    │   ├── mvnDebug
    │   ├── mvnDebug.bat
    │   └── mvnyjp

现在转到 bin 文件夹并查询版本

amar@admin:~/Downloads/apache-maven-3.0.4/bin$ ./mvn -v
Apache Maven 3.0.4 (r1232337; 2012-01-17 03:44:56-0500)
Maven home: /Users/amar/Downloads/apache-maven-3.0.4
Java version: 1.8.0_144, vendor: Oracle Corporation
Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/jre
Default locale: en_CA, platform encoding: UTF-8
OS name: "mac os x", version: "10.13.2", arch: "x86_64", family: "mac"

现在它工作正常，另一个步骤是卸载当前版本并使用 brew uninstall maven 和 brew unlink maven

取消链接

现在您可以在 bash_profile 中添加当前 Maven 二进制文件的路径并获取它。下面是例子

export M2_HOME=/Users/amar/Downloads/apache-maven-3.0.4
export PATH=$PATH:$M2_HOME/bin

再次尝试检查版本，对我有用

amar@admin:~$ mvn -v
Apache Maven 3.0.4 (r1232337; 2012-01-17 03:44:56-0500)
