Tim Allison created PDFBOX-5396:
-----------------------------------
Summary: Add maven enforcer rule to ensure that JAVA_HOME is set
Key: PDFBOX-5396
URL: https://issues.apache.org/jira/browse/PDFBOX-5396
Project: PDFBox
Issue Type: Task
Affects Versions: 2.0.25
Reporter: Tim Allison
I recently stubbed my toe on this one again. At least in the 2.x branch, the
module fontbox requires that the JAVA_HOME variable be set. If it isn't set,
the project build fails in fontbox without any meaningful indication as to why,
even with the -X option set in maven.

(default-compile) on project fontbox: Compilation failure -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to
execute goal org.apache.maven.plugins:maven-compiler-plugin:3.6.0:compile
(default-compile) on project fontbox: Compilation failure
at org.apache.maven.lifecycle.internal.MojoExecutor.execute
{noformat}
Also, on our website, there's no mention that JAVA_HOME should be set. And,
yes, I realize that it is set on most developers' systems. :D
One solution would be to add this rule to the maven-enforcer-plugin
configuration in the parent pom:
{code:java}
<requireEnvironmentVariable>
<variableName>JAVA_HOME</variableName>
<message>The JAVA_HOME environment variable must be
set!</message></requireEnvironmentVariable>
{code}
If this is ok, I'll add this rule in 2.x and see if I get the same behavior in
trunk.
Side note: This was probably the cause of:
https://www.mail-archive.com/[email protected]/msg11423.html and a few
other issues.
