eclipse运行maven报错，怎么解决

Posted 2023-02-16

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>compile</defaultGoal>

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"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

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。 参考技术A 这不碍事，警告，不是错误就行，程序可以跑
