解決方法
問題是將JRE作為JDK使用了,解決辦法是安裝JDK,并將JDK設置到Installed JREs中

錯誤堆棧
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1:compile (default-compile) on project hibernate: Compilation failure[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? [ERROR] -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

問題原因
如果是deploy 出現問題,那么可能是因為將部署路徑寫錯,如本例子,錯誤在于將SNAPSHOT版本寫成RELEASE版本
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-deploy-plugin:2.7:deploy (default-deploy) on project hibernate: Failed to retrieve remote metadata cn.blueboz.train:hibernate:0.0.1-SNAPSHOT/maven-metadata.xml: Could not transfer metadata cn.blueboz.train:hibernate:0.0.1-SNAPSHOT/maven-metadata.xml from/to blueboz-snapshots (http://bluebozpc:8081/repository/maven-releases): Failed to transfer http://bluebozpc:8081/repository/maven-releases/cn/blueboz/train/hibernate/0.0.1-SNAPSHOT/maven-metadata.xml.

新建項目卡頓問題
將maven的配置設置為offline,離線更新就可以了
Failure to transfer org.codehaus.plexus:plexus-archiver:jar:3.4 was cached in the local repository, resolution will not be reattempted until the update interval of [Bsdn] has elapsed or updates are forced. Original error: org.codehaus.plexus:plexus-archiver:jar:3.4 Bsdn (http://nexus.bsdn.org/content/groups/public/): No response received after 60000
一般是因為nexus 鏈接超時,建議直接換一個即可,在用戶路徑下的setting中,修改成aliyun
Alibaba central AliyunMaven http://maven.aliyun.com/nexus/content/groups/public/
實在不行的話,根據GAV,定位到本地緩存目錄,將
\M2_HOME.m2\repository\org\codehaus\plexus\plexus-archiver\3.4
目錄下的資源刪掉,重新UpdateProject即可
這個問題,網上提供了兩種方案先給出代碼,如果嘗試了之后發(fā)現可以的話,請按照這種方式解決。如果還是不行,請看我的第三種終極解決方案
1.解決方法一
$HOME目錄下的.m2目錄下的settings.xml文件的profiles節(jié)點下添加如下信息。Jdk版本
jdk1.8 true 1.8 1.8 1.8 1.8
2.解決方法二
在 build->pluginManager下添加,或修改maven-compiler-plugin的默認配置信息
maven-compiler-plugin 3.7.0
3.更新插件方法
必須前面兩個方法都嘗試了之后,還是無效的情況下。才可以。這時候,你必須考慮是不是你的IDE的問題了。筆者使用的是EclipseKepler版本,最高支持Jdk7。
點擊進入EclipseMarketPlace,輸入Maven
JavaTm 8 support for m2e for Eclipse Kepler SR2 ,安裝就可以了,建議還是翻墻安裝快些
