无法执行目标... maven-install-plugin ...无法安装工件......(访问被拒绝)

Question

在使用NetBeans编译maven项目时,我经常遇到以下错误:

Failed to execute goal 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 (Access is denied) -> [Help 1]

我不知道是什么原因造成的.解决方案是手动擦除有问题的.m2内容,问题就出现了.但这很烦人.

任何人都有永久解决方案？

Answer 1

您的-Dfile论点可能有错别字。确保它指向的是实际文件，而不是文件夹。

即确保您没有-Dfile=C:\lib\jackson意思-Dfile=C:\lib\jackson.jar

定位文件夹可能导致此“访问被拒绝”错误，对于实际的问题似乎没有任何意义。

NetBeans崩溃后,此问题开始发生.我最终删除了.m2的内容并从头开始重新安装了NetBeans.这个问题消失了.我仍然不清楚会导致什么,但它现在已经消失了.
