eclipse 运行Maven时报错总结

无法解析父级的POM文件，应该是是POM文件中使用了继承。

<parent>
        <groupId>com.iflytek.osspgroupId>
        <artifactId>ossp-resserver-allartifactId>
        <version>1.0.0-SNAPSHOTversion>

可以尝试加入

<parent>
        <groupId>com.iflytek.osspgroupId>
        <artifactId>ossp-resserver-allartifactId>
        <version>1.0.0-SNAPSHOTversion>
        ../ossp-resserver-all/pom.xml

出现类似的错误应该是Jre配置问题：

右击项目->Java Buid Path->Libraries->JRE->Edit->Install JREs...->Edit->JRE system libraries->Add External JREs..->找到缺少的jar（toos.jar）添加进去。

 

No goals have been specified for this build.

Maven Buid时出现下面这个错误：

[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>.

是因为没有指定buid goal,在POM文件中的buid节中加入默认值就行了。

<defaultGoal>compiledefaultGoal>

 

将第三方jar包发布到私服

1、首先要修改eclipse中的Maven配置。

不要使用内嵌的默认配置。

指向Maven的安装目录。

 

2、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"

3、发布第三方jar包

导入一个Maven项目之后发现有一个如下的错误：

Project configuration is not up-to-date with pom.xml. Run project configuration update

其实这个问题解决非常简单：

在项目上右键——【Maven】——【Update Project Configuration……】

这时会打开一个（Update Maven Dependencies）的对话框，然后勾选住出错的项目，点击Ok

这样就搞定了。
