Question

我已经使用

卸载了maven

brew uninstall maven

并尝试使用

重新安装它

brew install maven30

但是我收到了这个错误

 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

为什么我会在curl is not executable

中获得maven30

我也试过

 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mvn zip文件3.0.4，然后执行{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"

现在它运行正常，另一步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。以下是示例

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，它对我有用

amar@admin:~$ 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"
amar@admin:~$

无法从maven 3.5.2降级到maven 3.0.4：没有名称为＆＃34; maven30＆＃34;的可用公式
