Eclipse java开发问 Maven使用问题

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:UsersmoonDesktopossp-resservice-mavenossp-resserver-servicepom.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
