eclipse 运行Maven时报错总结

Non-resolvable parent POM

[INFO] Scanning for projects...[ERROR] The build could not read 1 project -> [Help 1][ERROR]   [ERROR]   The project com.iflytek.ossp:ossp-resserver-service:1.0.0-SNAPSHOT (C:\Users\moon\Desktop\ossp-resservice-maven\ossp-resserver-service\pom.xml) has 1 error[ERROR]     Non-resolvable parent POM: Could not find artifact com.iflytek.ossp:ossp-resserver-all:pom:1.0.0-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 11, column 10 -> [Help 2][ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.[ERROR] Re-run Maven using the -X switch to enable full debug logging.[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles:[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/ProjectBuildingException[ERROR] [Help 2] http://cwiki.apache.org/confluence/display/MAVEN/UnresolvableModelException

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

可以尝试加入<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>. Available lifecycle phases are: validate, initialize, generate-sources, process-sources, generate-resources, process-resources, compile, process-classes, generate-test-sources, process-test-sources, generate-test-resources, process-test-resources, test-compile, process-test-classes, test, prepare-package, package, pre-integration-test, integration-test, post-integration-test, verify, install, deploy, pre-clean, clean, post-clean, pre-site, site, post-site, site-deploy. -> [Help 1][ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.[ERROR] Re-run Maven using the -X switch to enable full debug logging.[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles:[ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/NoGoalSpecifiedException

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">  <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、发布第三方jar包
