解決Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install的錯誤
環境:idea編譯器,SSM框架。
一.報錯:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.4:install (default-install) on project XXX: Failed to install metadata XXX/maven-metadata.xml: Could not parse metadata 路徑\maven-metadata-local.xml: only whitespace content allowed before start tag and not \u0 (position: START_DOCUMENT seen \u0... @1:1) -> [Help 1]
[ERROR]

Java專案編譯時報錯。
二.原因:
不能編譯xx路徑下的maven-metadata-local.xml,這個maven-metadata-local.xml的作用是記錄了專案元資料,例如groupId,artifactId,version。我們的每次提交都會更新maven-metadata-local.xml,當在maven倉庫下載jar包時,也會根據這個檔案進行jar包的查詢。
沒有關專案,又直接運行了,maven-metadata-local.xml被佔用無法編譯。
三.解決:
找到路徑下的maven-metadata-local.xml,刪除掉,然後clean一下專案就可以了。
