与maven有JAVA_HOME不一致问题

Question

我即将发布一个项目,但似乎JAVA_HOME不一致.也许它被其他地方覆盖了？我使用的是ubuntu 14.04,我有openjdk-7,java-7-oracle,java-8-oracle.使用默认java设置update-java-alternatives

java -version

java version "1.8.0_25"
Java(TM) SE Runtime Environment (build 1.8.0_25-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.25-b02, mixed mode)

mvn -version给出以下输出

Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T17:37:52+00:00)
Maven home: /usr/share/maven3
Java version: 1.8.0_25, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-8-oracle/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.13.0-39-generic", arch: "amd64", family: "unix"

但是在做mvn发布时:准备,下面是我看到的:

[INFO] Not generating release POMs
[INFO] Executing goals 'clean verify'...
[WARNING] Maven will be executed in interactive mode, but no input stream has been configured for this MavenInvoker instance.
[INFO] Error: JAVA_HOME is not defined correctly.
[INFO]   We cannot execute /usr/lib/jvm/java-8-oracle/bin/java/bin/java

看起来像是在错误的文件夹中查找java执行器:/java/bin/java.我试过改变java home /usr/lib/jvm/java-8-orable/bin但是它破了mvn-version检查.

如何解决这个问题？谢谢阅读

我找不到这个来解决这个问题.有没有人遇到类似的东西？

我已经切换到java-7-oracle但仍然没有机会:

[INFO] Executing goals 'clean verify'...
[WARNING] Maven will be executed in interactive mode, but no input stream has been configured for this MavenInvoker instance.
[INFO] Error: JAVA_HOME is not defined correctly.
[INFO]   We cannot execute /usr/lib/jvm/java-7-oracle/bin/java/bin/java

亲爱的选民,我不是在寻求有关如何设置Java Home的帮助.它被设定为

/usr/lib/jvm/java-8-oracle

然后在我尝试使用java 7运行相同的东西时

/usr/lib/jvm/java-7-oracle

这是由webup8脚本在/etc/profile.d/jdk.sh中设置的

export J2SDKDIR=/usr/lib/jvm/java-7-oracle
export J2REDIR=/usr/lib/jvm/java-7-oracle/jre
export PATH=$PATH:/usr/lib/jvm/java-7-oracle/bin:/usr/lib/jvm/java-7-oracle/db/bin:/usr/lib/jvm/java-7-oracle/jre/bin
export JAVA_HOME=/usr/lib/jvm/java-7-oracle
export DERBY_HOME=/usr/lib/jvm/java-7-oracle/db

我已经切换到openjdk 7,编辑了jdk.sh以反映这一点export JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-amd64并且错误消失了.我跑到其他着名的问题(权限问题到标签文件夹.很奇怪).所以我认为它与maven本身无关.但这很奇怪,它适用于openjdk ......

Answer 1

JAVA_HOME必须指向jre,而不是jdk.然后设置:

export JAVA_HOME=/usr/lib/jvm/java-8-oracle/jre

Answer 2

.mavenrc在我的主文件夹上创建文件并添加下面的代码解决了我的问题.(Ubuntu 14.10,Maven 3.2.1)

export JAVA_HOME=/usr/lib/jvm/java-8-oracle

Answer 3

我使用 OpenJDK 作为默认 java ，更新了 /etc/environment 中的 JAVA_HOME ，所有问题都消失了。感谢您为我渡过难关所做的一切努力
