junit:
BUILD FAILED
/home/fuad/EclipseProject/DataCentre/build.xml:126: Could not create task or type of type: junit.
Ant could not find the task or a class this task relies upon.
This is common and has a number of causes; the usual
solutions are to read the manual pages then download and
install needed JAR files, or fix the build file:
– You have misspelt ‘junit’.
Fix: check your spelling.
– The task needs an external JAR file to execute
and this is not found at the right place in the classpath.
Fix: check the documentation for dependencies.
Fix: declare the task.
– The task is an Ant optional task and the JAR file and/or libraries
implementing the functionality were not found at the time you
yourself built your installation of Ant from the Ant sources.
Fix: Look in the ANT_HOME/lib for the ‘ant-‘ JAR corresponding to the
task and make sure it contains more than merely a META-INF/MANIFEST.MF.
If all it contains is the manifest, then rebuild Ant with the needed
libraries present in ${ant.home}/lib/optional/ , or alternatively,
download a pre-built release version from apache.org
– The build file was written for a later version of Ant
Fix: upgrade to at least the latest release version of Ant
– The task is not an Ant core or optional task
and needs to be declared using <taskdef>.
– You are attempting to use a task defined using
<presetdef> or <macrodef> but have spelt wrong or not
defined it at the point of use
Jadi kayaknya si ant tidak mengenali task “junitâ€. Ada dua kemungkinan memang versi antnya tidak mendukung yang kedua task junit membutuhkan library yang tidak ada.
Untuk yang pertama di komputer saya tidak mungkin karena sebelum di coba di eclipse, saya telah coba dari konsol dan berhasil. Kemnugkinan yang kedua saya buka opsi konfigurasi ant pada eclipse. Yaitu di
Run–>External Tools–>External Tools
Tampil Dialog, pilih file build xml project saya, lihat tab classpath dan memang tidak ada library junit.jar. Trus saya kopi file junit.jar ke folder WEB-INF/lib. Trus saya buka kembali dialog yang tadi.
Ke Tab classpath. Pilih User Entries. Klik tombol Add Jars, trus pilih file junit.jar dan OK, klik Apply, dan Run
(Success)
Spring-Tag-Error
Cek validitas DTD(Document Type Definition ) di file file konfigurasi xml
