在使用 NetBeans 编译 Maven 项目时，我经常遇到以下错误:
无法执行目标 org.apache.maven.plugins:maven-install-plugin:2.3.1:install (default-install) on project xxx: Failed to install artifact yyyy: C:\...\.m2\repository\...\yyyy-1.0.0.jar(访问被拒绝)-> [帮助 1]
我不知道是什么原因造成的。解决方案是手动删除有问题的 .m2 内容，然后问题就解决了。但这很烦人。
谁有永久的解决方案？

最佳答案
您的 -Dfile 参数中可能有错字。确保它指向实际的文件，而不是文件夹。
即确保你没有 -Dfile=C:\lib\jackson 当你的意思是 -Dfile=C:\lib\jackson.jar
以文件夹为目标可能会导致此“拒绝访问”错误，这对于实际问题似乎没有意义。
关于java - 无法执行目标...maven-install-plugin ...无法安装 Artifact ...(拒绝访问)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/5798150/
