|

| 589 | #
|
|---|
| 590 | # Undesirable behaviour can occur, however, when the 'ant' that is
|
|---|
| 591 | # run is the one found on PATH, and a different ant.jar is found (as
|
|---|
| 592 | # can occur when CLASSPATH is set). For this pattern of running the
|
|---|
| 593 | # 'ant' script the 'ant.jar' that is in Greenstone's web/WEB-INF
|
|---|
| 594 | # area is found. This Greenstone ant.jar file (at the time of
|
|---|
| 595 | # writing) is for ant v.1.8.2, and causes some of the Java
|
|---|
| 596 | # properities ant uses to changed. Even if your installed 'ant' is
|
|---|
| 597 | # (say v1.10.9) and the JDK you are running is JDK11, as a
|
|---|
| 598 | # consequence of finding the older ant.jar file, ant.version is set
|
|---|
| 599 | # to 1.8.2 and ant.java.version to 1.7. As a consequence of this,
|
|---|
| 600 | # the Greenstone3 build.xml fails to run as its minimum Java version
|
|---|
| 601 | # needs to be >=1.8
|

| 602 | #
|

| 603 | # In looking at how to address this issue, updating the version of ant.jar
|

|

| 605 | # a risk of a version mismatch between a system installed 'ant' and
|
|---|
| 606 | # the version of ant.jar Greenstone includes.
|
|---|
| 607 | #
|
|---|
| 608 | # The approach taken here, then, is to more carefully control the
|
|---|
| 609 | # launching of ant. By setting ANT_ARGS to -noclasspath, the 'ant'
|

| 610 | # script is directed not to use CLASSPATH, thereby avoidig the

|

|
|---|
| 615 | # doesn't arise. This is because the 'ant' script explicitly sets
