Hi,

I am trying to create a custom form field type in Liferay DXP 7.4. I am using dxp-7.4-u3. I created the form field module using the below command:

blade create -t form-field -v 7.4 -p com.liferay.demo.formfieldtype -c Time DDMTypeDemoText

module created successfully without any compilation error.

But when I try to build the module I am getting the below error:

> metalsoy --externalMsgFormat "Liferay.Language.get(‘\$2’)" --soyDeps "./node_modules/clay-*/src/**/*.soy" "./node_modules/com.liferay.dynamic.data.mapping.form.field.type/META-INF/resources/+(FieldBase|components)/**/*.soy"

Compiling soy
Error in plugin 'metal-tools-soy'

Finally, it shows build success but when I try to use the field while creating the form it shows render issue.

Any idea why this is happening? Thanks in advance.
