Maven使用問題彙總

Non-resolvable parent POM

沒法解析父級的POM文件，應該是是POM文件中使用了繼承。

<parent> <groupId>com.iflytek.ossp</groupId> <artifactId>ossp-resserver-all</artifactId> <version>1.0.0-SNAPSHOT</version> </parent>

能夠嘗試加入<relativePath>

<parent> <groupId>com.iflytek.ossp</groupId> <artifactId>ossp-resserver-all</artifactId> <version>1.0.0-SNAPSHOT</version> <relativePath>../ossp-resserver-all/pom.xml</relativePath> </parent>

出現相似的錯誤應該是Jre配置問題：

右擊項目 ->Java Buid Path->Libraries->JRE->Edit->Install JREs...->Edit->JRE system libraries->Add External JREs..->找到缺乏的jar（toos.jar）添加進去。

 

No goals have been specified for this build.

Maven Buid時出現下面這個錯誤：

[ERROR] No goals have been specified for this build. You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id>[:<plugin-version>]:<goal>.

是由於沒有指定buid goal,在POM文件中的buid節中加入默認值就好了。

<defaultGoal>compile</defaultGoal>

 

將第三方jar包發佈到私服

一、首先要修改eclipse中的Maven配置。

不要使用內嵌的默認配置。

指向Maven的安裝目錄。

 

二、配置Maven的setting.xml

<?xml version="1.0" encoding="UTF-8"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <pluginGroups> </pluginGroups> <proxies> </proxies> <servers> <server> <id>nexus-releases</id> <username>admin</username> <password>123</password> </server> <server> <id>nexus-snapshots</id> <username>admin</username> <password>123</password> </server> </servers> <mirrors> </mirrors> <profiles> <profile> <id>dev</id> <repositories> <repository> <id>local-nexus</id> <url>http://192.168.77.214:9088/nexus/content/groups/public/</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> </profile> </profiles> <activeProfiles> <activeProfile>dev</activeProfile> </activeProfiles> </settings>

 

三、發佈第三方jar包
