無法解析父級的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>

可以嘗試加入<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>

出現類似的錯誤應該是Jre配置問題：

右擊項目->Java Buid Path->Libraries->JRE->Edit->Install JREs...->Edit->JRE system libraries->Add External JREs..->找到缺少的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>.

是因爲沒有指定buid goal,在POM文件中的buid節中加入默認值就行了。

<defaultGoal>compile</defaultGoal>

 

將第三方jar包發佈到私服

1、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。

 

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">
  <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>

 

3、發佈第三方jar包
