JAVA_ Home is not defined correctly (only from Jenkins)

Tried to set Jenkins, but my build failed:

$ant test
Error: JAVA_HOME is not defined correctly.
  We cannot execute /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java
Build step 'Invoke Ant' marked build as failure

If I manually run "ant test" on the machine, it can run normally and Java_ Home is set to exactly the same value Do you know why Jenkins failed when he tried to run it? Are more environment variables involved (although I can't see it)?

Solution

For others, I must add path / usr / bin / to the path variable in Jenkins (find the correct path to which java to use)

Jenkins > Manage Jenkins > configure the system

Add environment variable > >

For example:

Name: path value: / usr / local / bin /: / usr / bin/
