1.情景再現:准備實現SprintBoot的熱部署功能,因沒有對應jar時,在Eclipse中mvn install 會報錯:
報錯信息:
[INFO] --- spring-boot-maven-plugin:1.4.1.RELEASE:run (default-cli) @ spring-boot --- [WARNING] The POM for org.springframework:springloaded:jar:1.2.4RELEASE is missing, no dependency information available [INFO] ------------------------------------------------------------------------ [INFO] BUILD FAILURE [INFO] ------------------------------------------------------------------------ [INFO] Total time: 1.328 s [INFO] Finished at: 2017-12-29T21:31:02+08:00 [INFO] Final Memory: 13M/33M [INFO] ------------------------------------------------------------------------ [ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.4.1.RELEASE:run (default-cli) on project spring-boot: Execution default-cli of goal org.springframework.boot:spring-boot-maven-plugin:1.4.1.RELEASE:run failed: Plugin org.springframework.boot:spring-boot-maven-plugin:1.4.1.RELEASE or one of its dependencies could not be resolved: Failure to find org.springframework:springloaded:jar:1.2.4RELEASE in https://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

2. 因Maven無法自動從網上倉庫下載到相應的jar包,所以需要手動進行安裝到本地MavenRepository中
命令格式如下:
mvn install:install-file -Dfile=jar包的位置(參數一) -DgroupId=groupId(參數二) -DartifactId=artifactId(參數三) -Dversion=version(參數四) -Dpackaging=jar
參數一:Jar包所在的位置
參數二:jar包的groupId
參數三:jar包的artifactId
參數四:jar包的版本號
3.實際操作:如下圖
4. 特別注意事項:
4.1 注意"-"不能缺少 install后面的"-"是沒有空格的
4.2 注意"-Dfile"中jar包的路徑和jar包的名字.
4.3 注意看cmd命令提示,查看本地repository中是否成功的復制了jar包.
